Relation Between Calorie And Joule

Q1

What is heat?

With a body’s temperature increase, the molecules or atoms’ vibrations increase. These vibrations are then transferred from one part of the body to another. The measure of energy with which the molecules vibrate in a system is termed as heat stored in that object.

Q2

What is Joule?

Joule is the SI unit of work or energy. One joule is defined as the amount of work done when a force of one newton acts on an object in the direction of its motion through a distance of one metre.

Q3

What is the relation between power and energy?

The relation between power and energy is that power has energy units divided by time.
The unit of power is Watts.
Unit of energy is Joules.
1 Watt = 1 Joule/1 second.

Q4

Can energy be stored?

Yes, energy can be stored. One efficient way to store energy is in the form of chemical energy in a battery. When connected to a circuit, energy stored in the battery is released to produce electricity. Energy can also be stored in many other ways. Batteries, gasoline, natural gas, food, water towers etc.

Q5

Define one calorie of heat.

One calorie of heat is defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius (or one kelvin).
