What happens to the pressure inside a sealed container of gas when it is heated?

• The pressure increases

• The pressure fluctuates

• The pressure decreases

• The pressure remains constant

If the pressure of a gas in a cylinder increases, what is the expected change in its temperature?

• The temperature increases

• The temperature decreases

• The temperature remains the same

• The temperature becomes zero

When the volume of a gas increases, the pressure will ______________

• Increase

• Decrease

• Stay the Same

Answer explanation

According to Boyle's Law, when the volume of a gas increases at constant temperature, the pressure decreases. This inverse relationship means that as volume goes up, pressure must go down.
