Why does a liquid change into Vapour on heating?
Hint: The liquid can be converted into the vapour state by applying the heat. Heat increases the kinetic energy of the particles and thus reduces the force of attraction between the particles. The particles get separated and escape to the vapour state. This process is called vaporization.
Can a liquid turns into Vapour without heating?
Explanation: Liquid is a matter that has no shape that can turn to solid or gas in a vapour form. Without heat liquid cannot change to gases,liquid need to be heated to high temperatures of up to one hundred degrees to make it evaporate to gases.
What happens when Vapour of liquid is cooled?
As vapour is cooled, the vapours condense and converts to liquid state. Now if we further cool down the liquid it will change to solid state at its freezing point. This is because on cooling the kinetic energy of the vapour decreases and intermolecular force of attraction increases.
What happens when Vapour of a liquid is cooled Class 6?
Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat.
Why is there water on the cup with ice in it but not on the cup without ice in it?
Why do you think the cup with the ice has bigger drops of water on the inside than the cup without ice? When the water vapor is cooled by the ice, the water molecules slow down more than in the cup without the ice. This allows their attractions to bring more molecules together to become liquid water.

Why does your soft drink sweat more in the summer?
Why does your soft drink can “sweat” more in the summer than in the winter? During summer season, water vapor presented in the atmosphere is more due to high evaporation rating. This evaporation rating increases the content of water vapor. The water vapor will form a layer on the surface of the can.
