Answer:
Question is not clear
it can be understood
Answer:
Explanation:
Answer
Ice ➝ Water
It is reversible
The name of this process is called melting
As it is reversible it is a Physical Change
Water ➝ Water Vapour
It is reversible
The name of This process is called as vapourzation
As it is reversible it ia a physical change
Water ➝ Steam
It is reversible
Steam and vapour are similar except that steam is hotter it is due to boiling and is called vaporization
And it is reversible it is also a physical change
Steam ➝ Water
It is also reversible
In this process a hotter substance gets colled and so is called condensation
Here as well as it is reversible it will be a Physical Change
Water ➝ Ice
It is also reversible
It is called as solidification as the temperature reduces
It is a physical change
Water Vapour ➝ Water
It is also reversible
It is also called as condensation
Its is a Physical Change
