Pure water boils at 100°C. What happens to the water particles when water boils?

A They gain energy and move further apart.

B They gain energy and stay close together.

CThey lose energy and move further apart.

DThey lose energy and stay close together.

choose one answer correctly!

The boiling of pure water has been resulted in the particles gaining energy and moving away from each other. Thus, option A is correct.

The boiling can be described as the conversion of the liquid state to the gaseous state. The molecules in the gaseous space are apart from each other and have no fixed shape.

The pure water has been transferred to the gaseous state at the temperature of 100 degrees celsius. The boiling has been introduced with the addition of the energy.

The water molecules gain energy and start to vibrate. The vibrations have resulted in the change in the change in phase of the liquid with evaporation.

Thus, when pure water boils, the water particles gain energy and move away from each other. Thus option A is correct.
