Question

A star is a huge ball of glowing gas held together by gravity.

• A. True
• B. False

Answer 1

The correct option is A True

1. Star: A star is nothing but a giant celestial body made up of Hydrogen and Helium gas.
2. Since a star is a massive ball of gas, the force of gravity (inward force) tries to squeeze the star as small as possible.
3. Inside the core of the star, tremendous pressure is build-up due to the fusion (combination) of hydrogen into helium and a large amount of heat generated which results in an outward pressure or force.
4. In simple words, there is a tug of war between the inward and outward force.
5. In a star force of gravity i.e inward force dominates outward force and holds the star together.
6. Hence the given statement is true.
