In the following question, a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct option out of the choices given below in each question.
Assertion (A) Three states of matter are the result of the balance between intermolecular forces and thermal energy of the molecules.
Reason (R) Intermolecular forces tend to keep the molecules together but the thermal energy of molecules tends to keep them apart.
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true and R is not the correct explanation of A
(c) A is true but R is false
(d) A is false but R is true

Reason (R) Intermolecular forces tend to keep the molecules together but the thermal energy of molecules tends to keep them apart.
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true and R is not the correct explanation of A
(c) A is true but R is false
(d) A is false but R is true
Answer: (a) Both A and R are true and R is the correct explanation of A
Both assertion and reason are true and the 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 them apart.
Answer: (a) Both A and R are true and R is the correct explanation of A
Both assertion and reason are true and the 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 them apart.
