Best Online Stock Trading Brokers for 2018 If you’re looking for a way to build more wealth in 2018, getting started with one of the best online brokerage accounts is a solid first step. Doing so will allow you to invest outside your traditional retirement accounts and on your own terms. The best part is, the best online brokerage firms charge little or no fees and offer excellent resources that can help you learn more about investing along the way. Of course, not all brokerage firms are created equal, and that’s why we took the time to break down each of their details and rank the top options on an array of factors. If you’re looking for a new way to invest this year and are ready to strike out on your own, the following online brokerage accounts should be at the top of your list.What Matters When You Trade Stocks on Your Own? Managing your own money can be a stressful endeavor. To minimize this, and to minimize information overload that tends to come from watching the markets 24/7, there are a few must-haves to look for in an online broker. Clean interface. When I trade, I want to be able to easily find my order entry ticket. I don’t want it buried under a number of drop downs. This interface should have intuitive access to see your balance, available cash, positions with real time P/L and all be easily navigated. Quick access to basic charting. A chart tells me where the stock has been recently. I don’t trade minute to minute anymore, so I don’t need complex tools like stochastics or retracement lines. All that’s important is that I have a basic chart on a yearly, monthly, weekly, daily and intra day time period. I use a chart to see current price relative to those time periods, mainly to avoid purchasing at a bad price. Low fees. One of the biggest roadblocks to building wealth is fees incurred to invest your hard-earned dollars. Because the fees charged by different brokerage firms vary so dramatically, it’s crucial to seek out options that charge low fees (or no fees) for account management and trades. There are over 50 online brokerages where you can open an account. Beyond the my three rules above, best online brokerage accounts aren’t just for trading stocks. Sure, many of them started as online stock trading accounts, but now they’re full-fledged trading, saving, investing, retirement planning, and banking machines. This industry is more complex than the average person thinks. You shouldn’t just pick any online broker and sign up for an account. The best online broker for one person is often completely different for the next person. Use this resource as a guide to your decision process. Figure out what features are best for you, and make your selection. What Makes a Great Online Broker? I analyzed a number of elements to come to my decision on which brokers are the best. Later in this post, I provide full details on how I selected the best online brokerages. When you take all the features, resources, trading platforms, and technology into account (while also considering every type of trader), the full-service brokers, like E*TRADE and TD Ameritrade are the best for the largest number of people. For those simply looking to make cheap trades, I would recommend going with Optionshouse. If you’re a very advanced trader, high-volume trader, or a professional who manages money, I recommend going with Interactive Brokers. However, I didn’t include Interactive Brokers on my list because they’re best for a very small group of traders and the platform is very complex. Top Qualities of Standout Online Trading Platforms Quality trading tools and technology Multiple trading platforms for all levels of traders Excellent mobile trading features Solid navigation that displays the relevant information where you want it Quality educational resources and research for trader development There’s more to selecting an online broker than price. You have to consider the resources you’re getting for the cost you pay per trade. For example, my colleague, who is also an ex-trader, likes to use a combination of stock and options trade in his longer-term trading. He recently switched over to Fidelity because he really liked the cash management features, but was very disappointed by complex order entry, sub-par options execution and frustrating navigation. He’s currently making the switch to one of the brokers I profile here.

Alat Dan Cara Mengukur Kalor Jenis Suatu Zat

Dengan mengetahui kalor jenis suatu zat maka kita sanggup dihitung banyaknya kalor yang dilepaskan atau diserap suatu zat tersebut dengan mengetahui massa zat dan perubahan suhunya dengan memakai persamaan:

Q = m . c . ΔT

dengan:
Q = kalor yang diserap atau dilepaskan
m = massa zat
ΔT = perubahan suhu

Alat yang sanggup dipakai untuk mengukur kalor jenis suatu zat yaitu kalorimeter. Salah satu bentuk kalorimeter ialah kalorimeter campuran. Berikut rujukan gambar denah kalorimeter sederhana ibarat tampak pada gambar di bawah ini.

Dengan mengetahui kalor jenis suatu zat maka kita sanggup dihitung banyaknya kalor yang dile Alat dan Cara Mengukur Kalor Jenis Suatu Zat
Bagan kalorimeter sederhana

Kalorimeter di atas terdiri dari:
  1. Sebuah ember kecil terbuat dari logam tipis yang di gosok mengkilat. Bejana inilah yang dinamakan kalorimeter.
  2. Sebuah ember yang agak besar yang berfungsi untuk meletakan kalorimeter. Di antara kedua ember itu dipasang isolator terbuat dari gabus yang berfungsi untuk mengurangi kehilangan kalor alasannya yaitu dihantarkan atau dipancarkan sekitarnya.
  3. Penutup dari isolator panas yang telah dilengkapi dengan termometer dan pengaduk. Pengaduk biasanya juga terbuat dari logam homogen dengan kalorimeter.


Pengukuran kalor jenis suatu zat dengan memakai kalorimeter bukan pengukuran secara eksklusif alasannya yaitu kita tidak akan mendapat kesannya secara eksklusif tetapi harus melaksanakan perhitungan terlebih dahulu dengan memakai variabel-variabel yang akan kita cari dalam pengukuran. Kita tidak tahu materi apa yang dipakai dan berapa kalor jenis dari kalorimeter. Bagaimana cara mengukur kalor jenis dari kalorimeter? Berikut beberapa tahapan memakai kalorimeter untuk mengukur kalor jenis kalorimeter.
  1. Bersihkan kalorimeter dari kotoran dan debu kemudian timbang untuk mengetahui massanya dengan memakai neraca yang sebelumnya sudah dikalibrasi terlebih dahulu.
  2. Kalorimeter diisi dengan air cuek (bukan air es) sampai separuhya, kemudian ditimbang. Sebelum ditimbang bab kalorimeter dibersihkan dari sisa-sisa percikan air. Nanti akan didapatkan massa air cuek dengan cara mengurangi massa total dengan massa kalorimeter. Nyatakan massa air cuek ini dengan notasi md
  3. Setelah melaksanakan penimbangan, ukur suhu air cuek yang ada di dalam kalorimeter dengan memakai termometer, kemudian kesannya dinyatakan dengan T1. Kemudian kalorimeter dimasukkan kembali ke dalam tempatnya, keadaan ini dilakkukan untuk menghindari dampak suhu luar.
  4. Ambil air cuek kemudian panaskan dengan memakai ember didih. Untuk acara ini harus berhati-hati, alasannya yaitu suhu air panas yang diukur sangat memilih hasil percobaan, selain pengukuran massa benda. Setelah air yang dipanaskan telah mendidih, termometer dimasukkan. Hasil pengukurannya dicatat dan dinyatakan dengan T2 (suhu air panas)
  5. Masukan sebgaian dari air mendidih tadi ke dalam kalorimeter. Kegiatan ini dilakukan dengan cepat untuk menghindari adanya dampak suhu yang sanggup merubah suhu T2.
  6. Setelah air panas dimasukkan dalam kalorimeter, aduklah secara perlahan-lahan biar air cuek yang suhu T1 sanggup bercampur dengan air panas yang bersuhu T2. Setelah yakin kedua air dengan suhu yang berbeda tadi benar-benar telah tercampur dengan merata, kemudian ukur suhunya dengan memakai termometer dan nyatakan kesannya sebagai T3 (suhu campuran)
  7. Kalorimeter dengan semua isnya (tanpa selubung) ditimbang kembali untuk mengetahui massa air panas yang dimasukan ke dalam kalorimeter. Cara mengetahui massa air panas yakni hasil pegukuran terakhir dikurangi dengan massa kalorimeter berisi air dingin. Nyatakan massa air panas ini dengan mp.


Dengan memakai aturan kekekalan energi kalor atau yang lebih dikenal dengan azas black kita sanggup mengukur kalor jenis kalorimeter tersebut, yakni dengan persamaan:
Qlepas= Qterima
Qair panas = Q air dingin + Q kalorimeter

Kita misalkan massa air panas = mp, massa air cuek = md, massa kalorimeter = mk, kalor jenis air = ca dan kalor jenis kalorimeter = ck, maka persamaannya menjadi:
ma.ca.(T2-T3) = ma.ca.(T3-T1) + mk.ck.(T3-T1)

Setelah didapatkan besarnya kalor jenis kalorimeter maka kita akan sanggup tentukan dari materi apa kalorimeter itu terbuat dengan cara membandingkan kalor jenis suatu materi yang terdapat dalam tabel di bawah ini dengan hasil perhitungan dari pengukuran tadi.
Dengan mengetahui kalor jenis suatu zat maka kita sanggup dihitung banyaknya kalor yang dile Alat dan Cara Mengukur Kalor Jenis Suatu Zat
Tabel nilai kalor jenis suatu zat

Agar kesannya benar-benar akurat, percobaan harus dilakukan secara teliti dan berulang-ulang.
