Question

What increases when a liquid at room temperature becomes a gas at its boiling point
​

Answer 1

Answer:

temperature

Explanation:

when the temperature increases the intermolecular space bwteen the molecules of the liquid increases due to decreased intermolecular force of attraction thus, the liquid changes it's state to a solid . this phenomena is often called evaporation this takes place when the liquid reaches it's boiling point

eg : bolling point of wayer is 100°C

Answer 2

Answer:

when heat is supplied to liquid at the room temperature, the temperature of the liquid INCREASE. the liquid changes its state to gas at its boiling point. Hence the average kinetic energy of the molecules changes (INCREASE).
