Explain how energy is transferred during the compression of a gas according to the particle model.

During the compression of a gas, work is done on the gas particles, which increases their kinetic energy. As the particles are forced closer together, they collide more frequently and with greater force against the walls of the container, resulting in an increase in pressure.

Cause lens: Name the cause, then state the effect on particles, pressure, density, or energy. This question asks: Explain how energy is transferred during the compression of a gas according to the particle model. The correct response is During the compression of a gas, work is done on the gas particles, which increases their kinetic energy. As the particles are forced closer together, they collide more frequently and with greater force against the walls of the container, resulting in an increase in pressure., 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) Use the particle model to explain energy transfer during gas compression. 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 628 is distinct because it uses this exact question context and the cause lens rather than a generic particle-model sentence.
