Measuring the average energy of motion of the particles in a substance is the same as measuring the substance's A. mass. B. pressure. C. heat capacity. D. temperature.

Answer:

Measuring the average energy of motion of the particles in a substance is the same as measuring the substance's D. Temperature

Explanation:

An object's temperature is the best approximation of the kinetic energy of the particles. When we measure an object's temperature, we measure the average kinetic energy of the particles in the object. The higher the temperature, the faster the molecules of the substance move, on the average.

The average kinetic energy of motion of the particles in a substance is measured by temperature.

The correct option for the question is (D) Temperature

Temperature  

  • Temperature is a physical quantity which shows the thermal energy present in all matters.

  • The temperature of an object is the best estimate of the particles' kinetic energy (which is the energy when the particle is in motion).

  • When we have to measure the average energy of motion of the particles in a substance, we will measure the temperature of the particle. The higher the temperature, the faster the molecules of the particles move.

Therefore, measuring the average energy of motion of the particles in the substance is the same as measuring the substance's temperature.
