Question

(a) water at room temperature is a liquid. --
(b) an iron almirah is a solid at room temperature. -​

Answer 1

(a) Water at room temperature exists as liquid because its melting point is below room temperature while boiling point (100º C) is above room temperature. Similarly, A fixed mass of water occupies a fixed volume.

(b) 1) As almirah is a solid, so it has a definite shape and volume. so it is solid at room temperature.

2) The melting point of iron is very high (1538°) while the room temperature is 28°. as melting point of iron is very high as compared to room temperature, it is solid at room temperature.
