The molecules have enough energy during boiling to leave the attractive forces of the liquid molecules and move into the gas phase molecules, becoming dispersed within the atmosphere with which the liquid is touching.
During boiling of water,water changes its state from liquid to gas due to a change in temperature. Therefore it is a physical change.

The fear of boiling water refers to either getting burned by the steam, or the boiling water.

There's actually no need to measure the temperature boiling water. If water is boiling, it will always be 100°. This is because boiling is a cooling process. As you apply heat, water molecules who want to boil, breaking free and enter the gaseous phase. When this happens, they take some of the energy that you imported into the liquid with them. Thus once the liquid reaches the boiling temperature water will continue to evaporate until there is no more water left. During this time, it will remain 100°.
The boiling point of sea water is higher compared with pure water. Temperature remain constant during boiling.
This coffee is dissolved in water.

During boiling the chemical composition is not changed.
Physical change because the water molecules stay unchanged during boiling, also the germination phase helps this be proved correct=)
A "water boiling alert" means to boil water. At 1 ATM of pressure, water does not boil until 212°F (100°C). At a higher altitude, the boiling point is lower, but not by much. No, when there is a "water boiling alert," boil the water.
correct! distillation is the prosses of evaporating a liquid to purify it then recondence it back to a liquid. This prosses can be used for removing salt from water.

The answer is that it lowers the boiling temperature and it makes food taste yummy!
During boiling the temprature remains constant and as soon as the water is bolied the temprature again rises.
