Question

Keeping the volume constant, the pressure of a gas varies______with temperature.(directly/inversely)

Answer 1

According to the ideal gas equation-

$\mathrm{PV}=\mathrm{nRT}$

If $\mathrm{V}=\mathrm{Constant}$

then,

P is directly proportional to temperature, which means if we increase the temperature of a gas at constant volume then the pressure will be increased.

Thus, keeping the volume constant, the pressure of a gas varies directly with temperature.
