Question

When a block of ice floats in a liquid od density $p_l$ melts completely, the level of (liquid+ water)

• A. Rises, if $p_l>p_w$
• B. falls, if $p_l<p_w$
• C. Remains unchanged, if $p_l=p_w$
• D. becomes very less

Answer 1

The correct option is A Rises, if $p_l>p_w$

When ice melts to water ,it will add up volume with the liquid.

If $Pl<Pw$, water will settle at bottom of container.

$Pl=Pw$, both settle at same level.

$Pl>Pw$, water stays at top of liquid.

but in all cases, the level of (liquid+water) system rises.
