Oh come one -_-''
Its obvious
- Bubbles of vaporised liquid will form
- The temperature of the liquid when boiling will remain constant even when more heat is applied.
- As the liquid is heated, the vapour pressure increases until it equals the pressure of the gas above it.

Why is the boiling point of water a physical change?
It's not a chemical change because the only the temperature and phase changes. The properties may be altered somewhat, but it the same chemical compound. No atomic bonds are broken or formed, there are no new substances formed, and none of the signs that indicate a chemical change are present. Some of the water is changing from a liquid to a gaseous state, and can be returned to a liquid state, unchanged, by cooling it.
