Explain how doing work on gas particles affects their kinetic energy.

When work is done on gas particles, energy is transferred to them, increasing their kinetic energy. This results in faster-moving particles, which can lead to an increase in temperature and pressure of the gas.

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: Explain how doing work on gas particles affects their kinetic energy. The correct response is When work is done on gas particles, energy is transferred to them, increasing their kinetic energy. This results in faster-moving particles, which can lead to an increase in temperature and pressure of the gas., because gas pressure comes from particle collisions with container walls. In Increasing the pressure of a gas (physics only) (HT only), the marking point should connect directly to (Physics only) (HT only) Link work done on gas particles to increased particle kinetic energy. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Particle model and pressure, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 611 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
