Physics for IGCSE & O level - Thermal Effects (Section 1 - No. 16)
How does increasing the temperature of a gas affect the pressure, assuming the volume is constant?
The pressure decreases.
The pressure increases.
The pressure remains the same.
The pressure fluctuates randomly.
Explanation
Increasing the temperature makes gas molecules move faster, leading to more frequent and forceful collisions, which increases pressure.
