How do I solve for V1 in this equation ​
arlik [135]

Answer:

<h2>V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}</h2>

Explanation:

\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}

<u>First of all cross multiply</u>

That's

P_{1}V_{1}T_{2} = P_{2}V_{2}T_{1}

<u>Next divide both sides by </u>P_{1}T_{2}<u>  in order to isolate </u>V_{1}

We have

\frac{P_{1}V_{1}T_{2}}{P_{1}T_{2}} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}

We have the final answer as

V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}

Hope this helps you
