Question

_____, water, and water vapour look different and display different physical properties but they are chemically the same.

Answer 1

Ice, water and water vapour are $3$ different states or physical forms with same molecular formula $H_{2}O$.

Water at temperature less than $0^{0}C$ exists as ice and water above ${100}^{0}C$ exists as water vapor.

So, the correct answer is Ice.
