Question: If the temperature of a gas is doubled at constant pressure, what happens to its volume?

Options:

Correct Answer: It doubles

Solution:

According to Charles\'s Law, at constant pressure, the volume of a gas is directly proportional to its temperature.

If the temperature of a gas is doubled at constant pressure, what happens to its volume?

If the temperature of a gas is doubled at constant pressure, what happens to its volume?

Step 1: Understand that we are dealing with a gas at constant pressure.
Step 2: Recall Charles's Law, which states that the volume of a gas increases as its temperature increases, as long as the pressure remains the same.
Step 3: Note that 'doubling the temperature' means if the original temperature is T, the new temperature will be 2T.
Step 4: Since the volume is directly proportional to the temperature, if the temperature doubles, the volume will also double.
Step 5: Conclude that if the temperature of the gas is doubled at constant pressure, the volume of the gas will also double.

Charles's Law – At constant pressure, the volume of a gas is directly proportional to its absolute temperature.
