The molecular theory states that the pressure exerted by a gas in closed vessel results from the gas molecules striking against the walls of the vessel. How will the pressure change if : the temperature is doubled keeping the volume constant

Explanation

To solve the problem of how the pressure of a gas changes when the temperature is doubled while keeping the volume constant, we can use Gay-Lussac's Law. Here’s a step-by-step solution:

### Step 1: Understand the relationship between pressure and temperature
According to Gay-Lussac's Law, the pressure of a gas is directly proportional to its absolute temperature when the volume is held constant. This can be expressed mathematically as:
\[ P \propto T \]
or
\[ \frac{P_1}{T_1} = \frac{P_2}{T_2} \]
