(a) Water is a liquid at room temperature due to following reasons :
(i) Water has fixed volume, but not fixed shape, it takes the shape of the container.
(ii) Water can flow easily, hence it is not rigid ‘but a fluid.
(b) An iron almirah is a solid at room temperature due to following reasons :
(i) An almirah has a fixed shape and a fixed volume.
(ii) It cannot flow, hence it is rigid.
