What units are used to measure specific latent heat, mass, and energy? Provide a brief explanation for each.

Specific latent heat is measured in joules per kilogram (J/kg), mass is measured in kilograms (kg), and energy is measured in joules (J). These units are important for ensuring that calculations involving energy transfer during phase changes are accurate and consistent.

Comparison lens: State both sides of the comparison so the contrast is explicit rather than implied. This question asks: What units are used to measure specific latent heat, mass, and energy? Provide a brief explanation for each. The correct response is Specific latent heat is measured in joules per kilogram (J/kg), mass is measured in kilograms (kg), and energy is measured in joules (J). These units are important for ensuring that calculations involving energy transfer during phase changes are accurate and consistent., because density links mass and volume, so the answer must preserve which quantity is being calculated. In Changes of state and specific latent heat, the marking point should connect directly to identify energy in joules, mass in kilograms and specific latent heat in joules per kilogram. 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 389 is distinct because it uses this exact question context and the comparison lens rather than a generic particle-model sentence.
