If the temperature of a gas is doubled at constant volume, what happens to the pressure?
It doubles
It halves
It remains the same
It quadruples
According to Gay-Lussac's Law, if the temperature of a gas is increased while keeping the volume constant, the pressure will also increase proportionally, thus it doubles.

Q
Q: If the temperature of a gas is doubled at constant volume, what happens to the pressure?
Solution: According to Gay-Lussac's Law, if the temperature of a gas is increased while keeping the volume constant, the pressure will also increase proportionally, thus it doubles.
Steps: 5
Step 1: Understand that we are dealing with a gas in a closed container where the volume does not change.
Step 2: Know that temperature is measured in Kelvin for gas laws, so if the temperature is doubled, we are increasing the temperature value.
Step 3: Recall Gay-Lussac's Law, which states that pressure is directly proportional to temperature when volume is constant.
Step 4: If the temperature doubles, the pressure must also double to maintain the relationship defined by Gay-Lussac's Law.
Step 5: Conclude that if the temperature of the gas is doubled, the pressure will also double.
