Question

A gas occupies 56 L at 73°C. What volume will the gas occupy if the temp. cools to 0°C?

Answer 1

44.2 L

Step-by-step explanation:

Use Charles Law:

`(V1)/(T1) =(V2)/(T2)`

We have all the values except for V₂; this is what we're solving for. Input the values:

`(56 L)/(346K) =(V2)/(273K)` - make sure that your temperature is in Kelvin

From here, we need to get V₂ by itself. To do this, multiply by 273 on both sides:

`(56*273)/(346) = V2`

Therefore, V₂ = 44.2 L

It's also helpful to know that temperature and volume are linearly related. So, when temperature drops, so will volume and vice versa.
