Question

Choose the incorrect statement(s).

• A. Gases expand on heating.
• B. Gases contract on heating.
• C. Gases do not respond to heating.
• D. Some gases contract and some expand on heating.

Answer 1

Answer: (B), (C), (D)

The correct options are
B

Gases contract on heating.

C

Gases do not respond to heating.

D

Some gases contract and some expand on heating.

Heating increases the kinetic energy of the gas molecules. More energy implies more random movement of the molecules. Thus on heating, it has a tendency to move further outward i.e expanding. So, here only option(A) is correct, all others are wrong.
