Explain how doing work on a gas transfers energy to the gas.

When work is done on a gas, such as through compression, energy is transferred to the gas particles. This energy increases the kinetic energy of the particles, resulting in an increase in temperature and pressure of the gas.

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: Explain how doing work on a gas transfers energy to the gas. The correct response is When work is done on a gas, such as through compression, energy is transferred to the gas particles. This energy increases the kinetic energy of the particles, resulting in 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) Explain that doing work on a gas transfers energy to the gas. 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 583 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
