Question

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?

Answer 1

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

Explanation:

At constant pressure `Vprop T`,

i.e. `V_1/T_1 =V_2/T_2`, absolute temperatures are used.

So `V_2` `=` `V_1/T_1xxT_2`

`=` `258*Lxx(395*K)/(351*K)` `=` `??L`

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