The Great Ice Cube Adventure: A Story of Changing States of Matter
Imagine you are playing with ice cubes on a warm summer day. You notice that the ice cubes start to melt and turn into water. What s happening here is a change in the state of matter, from solid (ice) to liquid (water). This happens because of the heat from the sun. But wait, there s more! If you leave the water in the open sun, after some time, it disappears. Where did it go? It turned into a gas and evaporated into the air! This is another state of matter change, from liquid to gas, again because of the heat. But don t worry, these changes can be reversed too! If you cool the gas, it will turn back into water, and if you freeze the water, it will become ice again. So next time you re playing with ice cubes, remember, you re also playing with science!
Question 1
What happens when heat is applied to ice cubes?
They turn into gas
They turn into plasma
They turn into water
Explanation. When heat is applied to ice (a solid), it changes its state to water (a liquid)
They disappear
They turn into air
Question 2
What happens to the water when it is left in open sunlight?
It freezes
It turns into ice
It evaporates
Explanation. When exposed to heat (like from the sun), water (a liquid) changes its state to gas, this process is known as evaporation
It changes color
It multiplies
Question 3
What happens if you cool the gas formed from water evaporation?
It turns into solid
It turns into water
Explanation. When gas is cooled, it changes its state back to liquid (water)
It disappears
It turns into ice
It turns into plasma
Question 4
What happens if you freeze water?
It turns into gas
It evaporates
It turns into solid
Explanation. When water is frozen, it changes its state from liquid to solid (ice)
It disappears
It turns into air
Question 5
Why does ice turn into water?
Because of cooling
Because of evaporation
Because of freezing
Because of heat
Explanation. Heat causes ice (a solid) to change its state to water (a liquid)
Because of condensation
