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.

Kalor Uap Dan Kalor Embun Suatu Zat

Menguap merupakan suatu insiden perubahan wujud zat dari cair menjadi gas. Sedangkan kebalikan dari menguap ialah mengembun, di mana mengembun merupakan insiden perubahan wujud zat dari gas menjadi cair. Dalam perubahan wujudnya, zat melepaskan atau memerlukan sejumlah kalor dengan tidak mengubah suhu zat tersebut. Untuk proses menguap zat tersebut memerlukan sejumlah kalor. Sebagai contoh, ketika kita memasak air dengan teko sampai mencapai titik didihnya, lalu sehabis itu air yang ada di dalam teko akan menguap membentuk gas yang keluar dari lisan teko. Agar dihasilkan uap air maka kita harus memanaskan atau memperlihatkan kalor pada air tersebut.
Menguap merupakan suatu insiden perubahan wujud zat dari cair menjadi gas Kalor Uap dan Kalor Embun Suatu Zat
Air yang menguap akhir diberikan sejumlah kalor
Sedangkan untuk proses mengembun zat melepaskan sejumlah kalor. Contoh insiden pengembunan ialah terbentuknya embun di pagi hari. Entah itu di daun, halaman rumah, atau tubuh mobil, sering terdapat titik-titik air di pagi hari yang kita kenal sebagai embun tersebut.

Banyaknya kalor yang diharapkan untuk menguapkan suatu zat sebanding dengan massa zat dan bergantung pada kalor laten uap (kalor uap), sedangkan banyaknya kalor yang dilepaskan untuk mengembunkan suatu zat juga sebanding dengan kalor laten embun (kalor embun). Definisi kalor uap ialah kalor yang diharapkan untuk mengubah wujud satu kilogram zat cair menjadi uap pada titik didihnya. Adapun kalor embun ialah kalor yang dilepaskan untuk mengubah wujud satu kilogram uap menjadi cair pada titik embunnya. Dalam hal ini nilai kalor uap dan kalor embun suatu zat besarnya sama. Misalnya, bila kalor uap air besarnya 540 kal/gr maka kalor embun air juga besarnya sama yakni 540 kal/gr. Kaprikornus untuk massa yang sama, dalam menguapkan suatu zat akan memerlukan kalor yang sama ibarat pada dikala melepaskan kalor pada proses pengembunan.

Jika kalor uap dan kalor embun suatu zat ditulis Lu, maka untuk menguapkan atau mengembunkan zat yang massanya m akan memerlukan atau melepaskan kalor sebanyak:
Q = mLu

dengan:
Q = kalor yang diperlukan/dilepaskan
m = massa zat
Lu = kalor laten uap (embun)

Kalor uap (embun) tiap zat mempunyai nilai yang berbeda-benda, berikut daftar kalor uap beberapa zat pada tekanan 1 atm dilengkapi dengan titik didihnya juga.

Tabel nilai kalor uap beberapa zat

Untuk memantapkan pemahaman Anda wacana kalor uap (kalor embun) dan kalor yang diharapkan atau dilepaskan suatu zat, silahkan simak pola soal berikut.

Contoh Soal 1
Air bermassa 100 gr dengan kalor uap sebesar 2,26 x 106 J/kg. Berapakah kalor yang dibutuhkan untuk menguapkan separo air tersebut?

Penyelesaian:
Diketahui:
m = ½ x 100 gr = 50 gr = 0,05 kg
Lu = 2,26 x 106 J/kg

Ditanya: Q = ?
Dijawab:
Q = m.Lu
Q = 0,05 kg . 2,26 x 106 J/kg
Q = 1,13 x 105 J = 113 kJ

Contoh Soal 2
Suatu zat cair mempunyai massa 80 gr. Untuk menguapkan seperempat zat cair tersebut memerlukan kalor sebesar 17 kJ. Tentuan nilai kalor uap zat cair tersebut.

Penyelesaian:
Diketahui:
m = ¼ x 80 gr = 0,02 kg
Q = 17 kJ = 17000 J
Ditanyakan: Lu = ?
Jawab:
Q = m.Lu
Lu = Q/m
Lu = 17000 J/0,02 kg
Lu = 850000 J/kg
Lu = 8,5 x 105 J/kg

Selain kita mengenal istilah kalor uap (embun), kita juga akan mengenal istilah kalor lebur (kalor beku). Silahkan pahami juga wacana kalor lebur dan kalor beku.
