How does heating affect the energy stored within a system?

The correct answer is It increases the energy stored by increasing particle energy.

Method lens: First identify the measured quantity, then match the equation or particle idea to the command word. This question asks: How does heating affect the energy stored within a system. The correct response is It increases the energy stored by increasing particle energy, because changes of state are explained by particle energy and arrangement. In Internal energy, the marking point should connect directly to apply the conservation of energy idea to heating and changes of state. 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 Internal energy and energy transfers, 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 272 is distinct because it uses this exact question context and the method lens rather than a generic particle-model sentence.
