Question

Activity - 2
Collect a few pieces of ice at your home. Take them into a vessel, light the gas and put that vessel on the
flame.
* Observe carefully when the vessel is heating. What happened? The ice will be melted and becomes as
water.
Heat the vessel continuously for some more time. What you have been observed? You will notice that the
water from surface gets converted into vapour.
What you learnt from this activity?
• What difference is observed in ice, water and water vapour?
– You will notice that water exist in '3' physical states, because ice contains water, water contains water,
and water vapor also contains water.
• What you have learned from Activity - 1 and Activity – 2?
Activity - I suggest that some substances are hard, some substances are thin and some substances are
similar to smoke (vapor), and Activity - 2, suggest that matter can exist in different physical state. So,
what are the reasons for existence of matter in different physical state?​
