Question

What other substances are around you that can change their states?​

Answer 1

Answer:

Phase changes include vaporization, condensation, melting, freezing, sublimation, and deposition. Evaporation, a type of vaporization, occurs when particles of a liquid reach a high enough energy to leave the surface of the liquid and change into the gas state. An example of evaporation is a puddle of water drying out.

Answer 2

The substances around us that can change states are water, alcohol( spirit), naphthalene, dry ice, iodine, etc.

• The given substances can change their state as-

water- change from liquid to ice or vapour

alcohol( spirit)- change from liquid to vapour

Naphthalene/dry ice/iodine/- change from solid to gas.

• Matter can exist in there states- solid, liquid and gas.

• Change in state can take place by the processes such as:

Melting- Solid to liquid

Freezing- Liquid to solid

Boiling/evaporation- Liquid to gas

Sublimation- Solid to gas

Condensation- Gas to liquid

Deposition- Gas to solid.
