Question

As the temperature of a gas sample increases, the number of molecules and volume remaining constant, the pressure exerted by the gasA. increasesB. decreasesC. stays the same

Answer 1

Answer:

A. increases

Explanation:

According to the Gay-Lussac's law:-

Thus, at constant volume and number of moles, Pressure of the gas is directly proportional to the temperature of  the gas.

P ∝ T

Also,  it can be written as:-

$\frac {P_1}{T_1}=\frac {P_2}{T_2}$

Thus, if the temperature is increased, the pressure exerted by the gas also increases.
