Question

What is the relationship between temperature, heat, and kinetic energy?

Answer 1

Hint: Heat, temperature, and kinetic energy are connected or link to each other. The temperature is linked to the average kinetic energy of the particles. When a material gets heated, some absorbed energy is stored inside the particles, while some energy increases the particles' motion. It increases the temperature of the material.

Complete answer:
Heat, kinetic energy, and temperature are correlating to each other. When we burn or heat a substance, we utilize some energy, which is used to increase the material's temperature and make a rise in its constituent molecules' kinetic energy. Temperature is the parameter of measurement of the kinetic energy of molecules. The molecules are constantly in motion, and higher temperature gives them more energy and vibrates more rapidly, and hence have higher kinetic energy. One effect of this rapid motion is the expansion observed during heating the substance.
Temperature is equivalent to heat and measures the molecules' average kinetic energy in a system. As heat includes in a system, the molecules receive the thermal energy and grow their kinetic energy. The measurement of temperature results comes from the transfer of kinetic energy between the system and the molecules or atoms within the measuring device. Hence the measure of temperature is equivalent to the measurement of the average kinetic energy within the system.
Kinetic energy is held by the body due to its movement in front of a reference frame. At the molecular level, the molecules have a displacement and do not move at the same speed, so they have a speed range; then, the concept of temperature conceives, that is, the measure of the particles' kinetic energy in that system. When a system absorbs heat, the particles begin to move faster and increase the kinetic energy, leading to an increase in temperature.

Additional Information:
Temperature and Heat are two different quantities. The significant difference between Heat and temperature is that Heat is the kind of energy that shifts from hot body to cold body. In comparison, temperature is the measure of the hotness and coldness of the body.

Note:
Solids, liquids, and gases have a temperature, and in a solid-state, there is no possible movement of the molecules. The molecules vibrate, then bonds will break, and therefore, the temperature rises till the melting point reaches where it proceeds from a solid-state to a liquid state; the liquids convert to gases at the boiling point.
