Question

With increase in temperature, the density of a substance in general :

• A. increases
• B. decreases
• C. first increases then decreases
• D. first decreases then increases

Answer 1

The correct option is B decreases

$Answer:-$ B

In general desity decreases with increase in temperature since $density=\frac{mass}{volume}$

Volume increases in general with increase in temperature and it is inversely proportional to density hence density decreases.

But for the case of water(when heated) it is different heating, its density first decreases and then increases.
