Question

Ice, water and water vapour look physically different but they are ___________ same

Answer 1

• Ice, water, and water vapor are three states of water i.e solid, liquid, and gas
• These three states are different in the physical state but their chemical nature is the same means the formula of water ${\mathrm{H}}_2\mathrm{O}$ is the same for ice, water, and water vapor

Therefore, ice, water, and water vapor look physically different but they are chemically the same
