Answer 1

Answer:

b

Explanation:

When the liquid water turns to solid ice we find that water freezes without getting any colder. That's because the latent heat of fusion is being lost from the liquid as it solidifies and the temperature of the water does not fall so quickly.

Hence, the correct option is B

Answer 2

Answer : option b .

There are many proves -

1. The water is freezing means it is losing heat .
2. If there was heat , the ice would melt but ice isn't melting so there is no heat .
3. If there was heat then never the water can freeze because ice would melt .
4. The ice always freezes in cold places . In cold places there is no heat . If there was heat, the heat would turn into cold .
5. If there was heat we would feel heat but we aren't feeling heat instead feeling cold , so there is cold , there is no heat .
