Answer 1

Liqiud water will change from a liquid to a solid at 0°C when heat energy has been removed.

Think about it liquid water expands when it turns into ice.

Answer 2

Answer: Option C

Step-by-step explanation:

Water is known to be the universal solvent which has the ability to exists in all the three forms. The water exists in the form of ice at 0 °C .

It can also change its state and gets converted into liquid at 100 °C. More than 100 °C the liquid state of the water will get converted into gaseous phase.

So, at 0 °C water from the liquid state starts getting converted into solid phase and the molecules in the solid are more closely packed as compared to liquid state.
