Question

In which glass was the level of water decreased the most? What do you think the reason is behind it​

Answer 1

$\sf\blue{Answer →}$

• Air around us gets heated from sunlight. This warm air provides heat for evaporation of water kept in the shade.

Answer 2

Answer:

It is true because in both the cases weight of water displaced = weight of ice and weight of ice before and after melting is the same.

This follows from Archimede's principle according to which a body floating in a liquid displaces weight of liquid equal to its own weight.

Water expands about 7% when it freezes, thats why it floats. But it displaces exaxctly its equivalent mass of water when it floats. When the ice melts there is no change in the amount of H2O in the vessel so the water level doesnt rise.

The level does not change because the ice is nearly at neutral bouyancy or barely floating to begin with, and it is colder.
