According to Boyle's law, if the volume of a gas is doubled, what happens to its pressure?
Correct Answer: Pressure is halved.
- Step 1: Understand Boyle's law, which says that pressure and volume of a gas are related when temperature is constant.
- Step 2: Remember that if the volume increases, the pressure decreases, and vice versa. This is called 'inversely proportional'.
- Step 3: If the volume of the gas is doubled, it means the gas takes up more space.
- Step 4: Since the volume is now larger, the pressure must decrease to keep the relationship constant.
- Step 5: Specifically, if the volume is doubled, the pressure is halved.
- Boyle's Law – Boyle's law describes the inverse relationship between the pressure and volume of a gas at constant temperature.
