Multiple Select

We can change one form of water into another form by-

• HEATING

• COOLING

• ONLY HEATING

• ONLY C

Multiple Choice

Ice changes into water on heating.

What is this process called?

• Evaporation

• Condensation

• Melting

• None

Open Ended

Water changes into water vapour on heating.

What is this process called?

CHANGE OF FORM OF WATER DUE TO COOLING

​

What happens to water when we freeze it?

If we keep water in the freezer, it cools down and freezes to form ice.This is called freezing.

  

Change of gas into liquid.

​Cooling the water vapour(gas)-CONDENSATION

When we cool water vapour it condenses (cool)to form water droplets.This is called condensation.

​

​Water vapour changing to tiny droplets of water.

Multiple Choice

When water vapour cool down they change into-_____________

• ice

• gas

• droplets of water

• None

Open Ended

What is the difference between evaporation and condensation?

Open Ended

Rahul took out a bottle from the freezer and observed some tiny droplets on the surface of bottle. Help him to find out how are these droplets formed.
