Gas Pressure and Temperature | GCSE Physics Practice
Heating a gas increases the kinetic energy and speed of its particles, increasing the pressure.
How does doubling temperature affect particle collisions?
What is Gas Pressure and Temperature | Practice?
"The relationship between the temperature of a gas and the pressure it exerts on its container."
What is the formula for density?
Why does a crisp packet puff up when taken on an airplane flight?
Calculate the pressure at a depth of 2m in water (density = 1000 kg/m³, g = 9.8 N/kg).
Specific heat capacity is the energy needed to raise 1kg of a substance by ____.
Kinetic Particle Theory
Pressure is caused by particles colliding with the walls of the container.
Higher temperature = faster particles.
Faster particles collide more frequently and with more force.
This increases the total pressure of the gas.
Exam Logic: Always mention both the FREQUENCY of collisions and the FORCE of each collision to get full marks.
