Question

  1. A. Temperature increases ? P43-027 state-change particle arrangement
  2. B. P43-027 trap: this swaps state-change particle arrangement for a neighbouring particle-model idea.
  3. C. P43-027 trap: this omits heating from the explanation.
  4. D. P43-027 trap: this answer belongs outside Internal energy.

Answer

The correct answer is Temperature increases ? P43-027 state-change particle arrangement.

Explanation

Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: What is the effect of energy transfer on temperature without changing state (Internal energy) ?. The correct response is Temperature increases ? P43-027 state-change particle arrangement, 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 273 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.

Common mistake

Confusing Energy Transfer with Temperature Change

Students often think that when energy is transferred to a system, the temperature must always increase.

Understand that energy transfer can change the state of a substance without changing its temperature, such as during melting or boiling.
