At constant pressure, if the temperature of a gas is increased, what happens to its volume?
Correct Answer: Volume increases
- Step 1: Understand that we are looking at a gas at constant pressure.
- Step 2: Know that temperature is a measure of how hot or cold something is.
- Step 3: Recognize that when the temperature of the gas increases, the gas particles move faster.
- Step 4: Realize that as the gas particles move faster, they need more space to move around.
- Step 5: Conclude that because the gas particles need more space, the volume of the gas increases.
- Charles's Law – At constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.
