# A container is filled with 258 liters of nitrogen gas at a temperature of 78°C. What would the volume (in liters) of the gas be if the temperature changed to 122°C?

Use Charles' Law. I got under $300$ $L$.

#### Explanation:

At constant pressure $V \propto T$,

i.e. ${V}_{1} / {T}_{1} = {V}_{2} / {T}_{2}$, absolute temperatures are used.

So ${V}_{2}$ $=$ ${V}_{1} / {T}_{1} \times {T}_{2}$

$=$ $258 \cdot L \times \frac{395 \cdot K}{351 \cdot K}$ $=$ ??L

As long as the temperature is in degrees Kelvin, I could use any units of volume, litres, cubic metres, pints, gallons, gills.
