Question

Which one is the non-renewable source of energy?
A. Solar energy
B. Biomass
C. Natural gas
D. Wind energy

Answer 1

Hint:Energy is the need of our daily life. In Physics we define it as the ability to do work. Energy can only be transferred from one form to another. Energy has different forms like kinetics energy, potential energy, thermal energy, solar energy, etc. Again, we categories energies into two categories renewable and non-renewable sources, these two we will discuss here.


 Complete step by step solution:
There are two types of energy sources, renewable and non-renewable sources. Renewable sources are naturally replenished on a human time scale but non-renewable sources are not replenished that fast, as a result, we will run out of it one day. Non-renewable sources of energy are natural resources. It takes thousands of years to form naturally and cannot be replaced as fast as being consumed.
Examples of renewable sources are sunlight, wind, rain, biomass, etc.
Examples of non-renewable sources of energy are earth minerals, ores, coal, petroleum, natural gas, etc.
Hence, option (C) Natural gas is the correct option.

Note:
In physics, energy must be transferred to an object to get some work done.
SI unit of energy is joule.
It is a conserved quantity, which follows the conservation law.
Forms of energy are
Kinetic energy due to objects motion
Potential energy due to its configuration
Chemical energy
Elastic energy due to stretching an object
Thermal energy due to the temperature of the object etc.
The total kinetic and potential energy of a system is known as mechanical energy.
The primary source of energy is sun, wind, water, geothermal energy, coal, oil, natural gas, and biomass, etc.
It can neither be created nor be destroyed.
