Question

Heat is a form of energy.
(A) True
(B) False

Answer 1

Hint:First of all define the term energy and then relate it with heat. During increase in temperature, thermal energy is produced and due to which atoms and molecules move fast. The energy that comes due to the increase in temperature of the substance is known as thermal energy.

Complete step by step answer:Energy is the capacity for doing work. Energy exists in the form of potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. Heat energy which is transferred from one body to another as the result of a difference of temperature. When two bodies are at different temperatures are brought together, energy is transferred from the hotter body to the colder body. Thermal energy is that energy that comes from a substance whose molecules are vibrating due to rise in temperature. When temperature is low then molecules of the substance do not move or move very slowly but as soon as the temperature increases then the molecules of the substance move faster such that they start vibrating fast. Heat energy is a form of energy.
Thus, it is a true fact that heat is a form of energy.
Therefore, option (A) is the correct choice.

Note:Heat is the motion of particles that creates a form of energy known as heat or thermal energy. However, particles in solids, liquids and gases are always in motion. And the motion of particles that creates a form of energy called thermal (i.e. heat) energy that is present in all matter. The biggest example of heat energy is the sun in our solar system as the sun radiates heat to warm us up on the planet earth.
