Question

A body has a relative density of $x$ with respect to water at ${25}^{o}C$. What is the effect on the relative density of the body with respect to water at ${50}^o$ C?

• A. It increases
• B. It decreases
• C. No effect.
• D. Depends on the time of heating.

Answer 1

Answer: (A)

It increases

Relative density with respect to water is defined as the ratio of density of substance to that of water.

Relative density of substance with respect to water increases with increase in temperature because density of water decreases with increase in temperature.
