Question

Property of matter to increase in size on heating is called

• A. Thermal work
• B. Thermal Expansion
• C. Thermal radiation
• D. Thermal contraction

Answer 1

The correct option is B

Thermal Expansion

The explanation for correct option

Option B: Thermal expansion

1. Expansion is a word used to describe growth in size.
2. Thermal expansion refers to the growth in the size of an object due to heating

The explanation for incorrect options are:

Option A: Thermal work

Thermal work refers to the work done on the basis of heat energy

Option C: Thermal radiation

Thermal radiation refers to the transfer of heat without affecting the medium.

Option D: Thermal contraction

Thermal contraction is not possible since contraction occurs when there is a loss of heat, i.e., cooling of a body.

Hence the correct option is Option B. Thermal Expansion.
