Explain the difference between energy and power.

Interpretation Introduction

Interpretation:

The difference between energy and power is to be explained.

Concept introduction:

Power is defined as the energy used per unit time to do some work. SI unit of power is watt (W) which is joule/second.

The power that arises by utilizing the chemical or physical resources for providing heat and light or carrying out various processes is known as energy. The SI unit of energy is joule.

The law of conservation of energy states that energy can neither be created nor be destroyed, it can be converted to other forms.

Explanation of Solution

The ability to perform any work is known as energy. Joule is the basic unit of energy and it is denoted by J. According to first law of thermodynamics energy can neither be created nor be destroyed, it can only be converted from one form into other forms. The other unit of energy is calorie...
