Question

What happens to water molecules when water is heated from ${90^ \circ }C$to ${110^ \circ }C$?

Answer 1

Hint :The temperature at which the pressure imposed by the surroundings on a liquid equals the pressure exerted by the liquid's vapour is known as the boiling point. The addition of heat helps in the transition of the liquid into its vapor without raising the temperature.

Complete Step By Step Answer:
Water is composed of hydrogen and oxygen and occurs in three states: gaseous, liquid, and solid. Water is one of the most abundant and necessary chemicals, appearing as a liquid on the Earth's surface under natural conditions, making it invaluable for human needs as well as plant and animal needs.
Water molecules are made up of polar oxygen and hydrogen atoms, with one side hydrogen having a positive electrical charge and the other side oxygen having a negative charge. This causes the water molecule to be attracted to a wide range of other molecules.
When water is heated from ${90^ \circ }C$to ${110^ \circ }C$, it begins to boil. Water vapor bubbles emerge in boiling water. This occurs as liquid water molecules accumulate enough energy to fully overpower the force of attraction between them and transition to the gaseous state. The bubbles emerge from the water and exit as steam from the pot. The mechanism by which a liquid boils and transforms into a gas is known as vaporization. The boiling point of a liquid is the temperature at which it begins to boil.

Note :
It is important to note that, as the temperature or pressure of a system varies, phase changes occur. As the temperature or pressure rises, so does the contact between the molecules. Similarly, as the temperature drops, it becomes possible for molecules and atoms to form a more rigid structure.
