When the volume of a gas is halved at constant temperature, what happens to the pressure (Pressure in gases (physics only)) ? P43-047 Pressure in gases (physics only) checkpoint

The correct answer is It doubles ? P43-047 density measurement and calculation.

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: When the volume of a gas is halved at constant temperature, what happens to the pressure (Pressure in gases (physics only)) ?. The correct response is It doubles ? P43-047 density measurement and calculation, because density links mass and volume, so the answer must preserve which quantity is being calculated. In Pressure in gases (physics only), the marking point should connect directly to (Physics only) Explain why decreasing the volume of a gas at constant temperature increases its pressure. 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 523 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
