Question

Which form of energy is involved in transfer of energy between two bodies due to a temperature difference?
A. Potential energy
B. Nuclear energy
C. Chemical energy
D. Heat energy
E. Temperature energy

Answer 1

Hint: Energy flow is accompanied by flow of molecules of matter from one end to another. Temperature is the degree of hotness or coldness of a body and is measured using Celsius scale, Kelvin scale and Fahrenheit scale.

Complete step by step answer:The energy that arises when there is a temperature gradient between ends is called heat or thermal energy.
The energy owes its behavior to the temperature difference between two bodies of considerably different temperature magnitude.
For example when an athlete decides to run 100m , he will be seen dry and calm before the race because the molecules as well as the ions in his body are at rest, but immediately when he starts running the molecules are excited and they start moving with certain amount of velocity and speed and as agitation or vibration of the molecules occur, temperature is seen to increase from a very low value to a high value and ends up producing sweat which is a product of heat and in the process momentum and kinetic energy ( energy produced by the athlete because of his motion) are recorded.
Thus heat energy is involved in transfer of energy between two bodies due to a temperature difference.
Therefore, the correct option is Option D.

Note:Energy transfer is Paramount between two bodies or points in a medium and it occurs between an object in and outside. Can be seen and observed in a pot filled with water and place on a stove or burner
