Question

An explosion is a rapid chemical reaction that results in a considerable increase in volume of gases.

a. True
b. False

Answer 1

The statement is true. An explosion is a rapid chemical reaction that results in a considerable increase in volume of gases.

Step-by-step explanation:

Explosion can be defined as high pressure opening of a matter with release in many gases which is increase in the volume of gas.

With explosion there is release of huge amount of energy.

This energy can be in the form of heat energy or sound energy.

Hence the statement that explosion is a chemical change which results in the increase in volume is correct.

Answer 2

a. True i.e An explosion is a rapid chemical reaction that results in a considerable increase in volume of gases.

Explanation

When an explosion occurs, the materials and gas which are initially contained in a small volume expand outwards very rapidly from their point of origin. A chemical process that is an explosion will start at one point and rapidly expand to cover more space. This tells us that the correct answer is a. True.
