Question

When water boils, what does it become? 

Answer 1

When water boils, it becomes steam. Boiling is a process in which water is heated to its boiling point (212°F or 100°C) and turns into a vapor. Steam is a gas composed of water molecules.

Answer 2

When water boils, it becomes steam or water vapor. Boiling is a change of state from liquid to gas and occurs when the temperature of water reaches its boiling point, which is 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure. The heat energy causes the water molecules to gain enough energy to break free from their bonds and turn into gas. This change in state is important for various industries and also for daily life activities such as cooking, cleaning, and generating electricity.
