Question:

Give reason for confirmation—

(a) Water is liquid at room temperature.

(b) an iron almirah is solid at room temperature.

Answer:

(a) At normal temperature water remains in liquid phase and it does not have any definite shape. It occupies the shape of jar in which it is contained. It flows easily so it is better to say it fluid instead of saying liquid.

(b) Iron almirah is solid at room temperature because both their size and volume are definite and they are rigid, do not flow.
