Question

Water at sea level heated to 100°C would be:

a) In solid state
b) In gaseous state
c) In liquid state
d) In plasma state

Answer 1

Water at sea level heated to 100°C converts to a gas, which is known as steam due to the process of vaporization. Therefore, the correct answer to the question is option b) In gaseous state.

Step-by-step explanation:

Water at sea level heated to 100°C would be in the gaseous state. At low temperatures (below 0°C), water is solid (ice). At "normal" temperatures (between 0°C and 100°C), water is in the liquid state.

However, at temperatures above 100°C, water turns into a gas, known as steam. The state of water at varying temperatures is determined by the amount of heat it absorbs or releases. The physical process in which a liquid turns into a gas at its boiling point is known as vaporization.

Hence, water heated to 100°C at sea level will be in a gaseous state, corresponding to option b).
