give reason water at room temperature is a liquid
(a) At room temperature (25 C), water is a liquid because it has the following characteristic of liquid:
(i) At room temperature, water has no shape but has a fixed volume that is, it occupies the shape of the container in which it is kept.
(ii) At room temperature, water flows.
(b) An iron almirah is a solid at room temperature (25 C) because:
(i) it has a definite shape and volume like a solid at room temperature.
(ii) it is rigid as solid at room temperature.
(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.
