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

A. increases

Step-by-step 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.
