Which of the following correctly distinguishes temperature from internal energy (Temperature changes in a system and specific heat capacity)

The correct answer is Temperature is the average kinetic energy of particles, while internal energy is the total energy..

Graph lens: Read the trend, flat section, gradient, or axis labels before explaining the physical meaning. This question asks: Which of the following correctly distinguishes temperature from internal energy (Temperature changes in a system and specific heat capacity). The correct response is Temperature is the average kinetic energy of particles, while internal energy is the total energy., because density links mass and volume, so the answer must preserve which quantity is being calculated. In Temperature changes in a system and specific heat capacity, the marking point should connect directly to identify change in thermal energy in joules, mass in kilograms, specific heat capacity in joules per kilogram per degree Celsius and temperature change in degrees Celsius. 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 291 is distinct because it uses this exact question context and the graph lens rather than a generic particle-model sentence.
