Assertion (A) Three states of matter are...

Assertion (A) Three states of matter are the result of balance between intermolecular forces and thermal energy of the molecules.
Reason (R) Intermolecular forces tend to keep the molecules together but thermal energy of molecules tends to keep tham apart.

Both A and R are true and R is the correct explanation of A

Both A and R are true but R is not the correct explanation of A

A is true but R is false

A is false but R is true

Text Solution

Verified by Experts

The correct Answer is:

Both assertion and reason are true and reason is the correct explanation of assertion. Intermolecular forces and thermal energy decide the state of matter because the former kept the molecules together but later keep tham apart.
