How does increasing temperature affect the average kinetic energy of particles in a substance (Internal energy) ? P43-042 Internal energy checkpoint

The correct answer is It increases the average kinetic energy ? P43-042 specific heat capacity reasoning.

Graph lens: Read the trend, flat section, gradient, or axis labels before explaining the physical meaning. This question asks: How does increasing temperature affect the average kinetic energy of particles in a substance (Internal energy) ?. The correct response is It increases the average kinetic energy ? P43-042 specific heat capacity reasoning, because changes of state are explained by particle energy and arrangement. In Internal energy, the marking point should connect directly to explain why energy transfer can change state without changing temperature. 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 255 is distinct because it uses this exact question context and the graph lens rather than a generic particle-model sentence.
