Answered by admin @
Answer:
(a)At room temperature (25°C), water is a liquid because it has the following characteristics of liquid: At room temperature, water has no shape but has a fixed volume i.e., it occupies the shape of the container in which it is kept. At room temperature, water flows easily.
(b)An iron almirah is a solid at room temperature because its melting point as well as boiling point is above room temperature. Similarly, (i) An iron almirah is rigid and has a fixed shape. (ii) The density of metal is quite high. Hence, iron almirah is a solid at room temperature.
