Question

. Give two reasons to justify-
(a) water at room temperature is a liquid.
(b) an iron almirah is a solid at room temperature.​

Answer 1

Explanation:

(a) Water at room temperature is a liquid because it boils at 373 K and the room temperature is nearly 20∘C−25∘C. ... (b) An iron almirah is a solid at room temperature because it has a definite shape and definite volume. So the properties mentioned are satisfied by the solid-state only.

Answer 2

Answer:

(a) water at room temperature is liquid because at this temperature (i)it has fixed volume and (ii)it can flow. (B) An iron almirah is solid at room temperature because at this temperature (i) it has definite shape along with fixed volume and (ii) It can not flow like water and hence does not possess fluidity
