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 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.

Answer 2

a) 1.water at room temperature has fixed volume but not fixed shape.
2. it has moderate compressibility and fluidity without any rigidity.

b)1.almirah have fixed shape and fixed volume.
2. it is highly rigid and not compressible.
