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.

Pemuaian Volume Gas Pada Suhu Tetap

Untuk jumlah gas tertentu, menurut hasil eksperimen yang dilakukan oleh ilmuwan fisika yang berjulukan Robert Boyle (1627 - 1691) didapatkan bahwa volume gas berbanding terbalik dengan tekanan yang diberikan pada gas tersebut ketika suhu dijaga konstan, yaitu:

V ≈ (1/P)

dengan P yakni tekanan diktatorial (tekanan yang dipengaruhi oleh besarnya tekanan udara luar atau tekanan yang terukur ditambah dengan tekanan luar). Jika tekanan gas digandakan menjadi dua kali semula, volume diperkecil hingga setengah nilai awalnya. Karena ini merupakan hasil eksperimen Robert Boyle maka hubungan ini dikenal sebagai Hukum Boyle. Grafik tekanan (P ) terhadap volume gas (V ) untuk suhu tetap tampak menyerupai pada gambar di bawah ini.
menurut hasil eksperimen yang dilakukan oleh ilmuwan fisika yang berjulukan Robert Boyle Pemuaian Volume Gas Pada Suhu Tetap
Grafik P terhadap V dengan T tetap

Hukum Boyle juga sanggup dituliskan:

PV = konstan
atau
P1V1 = P2V2

dengan:
P1 = tekanan gas awal (Pa)
P2 = tekanan gas final (Pa)
V1 = volume gas awal (m3)
V2 = volume gas final (m3)

Persamaan PV = konstan, mengatakan bahwa pada suhu tetap, bila tekanan gas dibiarkan berubah maka volume gas juga berubah atau sebaliknya, sehingga hasil kali PV tetap konstan.

Untuk memantapkan pemahaman Anda perihal pemuaian volume gas pada suhu tetap, silahkan simak dan pahami tumpuan soal di bawah ini.

Contoh Soal 1
Sejumlah gas dalam ruang tertutup pada ketika volumnya 40 dm3, tekanannya 2 atm. Jika gas ditekan secara perlahan-lahan sehingga volumnya menjadi 25 dm3 tanpa mengalami perubahan suhu, maka berapakah tekanan gas yang terjadi?

Penyelesaian:
Diketahui:
V1 = 40 dm3
P1 = 2 atm
V2 = 25 dm3

Ditanyakan: P2 = ?

Jawab:
P1V1 = P2V2
2 atm. 40 dm3 = P2.25 dm3
P2 = (2 atm. 40 dm3)/25 dm3
P2 = 3,2 atm

Contoh Soal 2
Gas dalam ruang tertutup memiliki tekanan 1 cmHg. Jika lalu gas tersebut ditekan pada suhu tetap sehingga volum gas menjadi ¼ volum mula-mula, berapa tekanan gas yang terjadi?

Penyelesaian:
Diketahui:
P1 = 1 cmHg
V2 = ¼.V1

Ditanyakan: P2 = ?

Jawab:
P1V1 = P2V2
1 cmHg.V1 = P2. ¼.V1
P2 = 1 cmHg/¼
P2 = 1 cmHg × 4
P2 = 4 cmHg
