Answer 2

Answer:

1. The pieces of wax starts to melt.
2. Initially the wax was in solid state.
3. It converted into liquid state.
4. It again becomes solid.

Explanation:

When we take pieces of wax in a bowl and heat  them on a candle or spirit lamp,

(1): On heating under candle or spirit lamp the pieces of wax starts melting because wax contains a large amount of hydrogen and carbon atoms which helps it in melting easily.

(2): Initially, the wax was in solid-state as it had its own shape before melting.

(3): After melting, it will convert in the liquid state.

(4): On placing the bowl, containing the melted wax, in the cold water the wax starts to freeze which means it starts to acquire the shape of the bowl and therefore it will become solid wax.
