NEET Physics Thermal Expansion MCQ Question
Which of the following statements about thermal expansion is correct?
Thermal expansion in solids occurs only in the length dimension.
Volume expansion is always three times greater than linear expansion for solids.
A change in temperature can cause a body to expand in length, area, and volume.
Thermal expansion does not occur in liquids or gases.
Correct Answer
Detailed Explanation
A change in temperature causes a body to change its dimensions, leading to linear, area, and volume expansions as described in the NCERT context. The relationship between the different types of expansion is crucial in understanding thermal properties of matter.
