Solution :-

(a) Transition in the states of matter of water occurs at 0°C and 100°C.

At room temperature, water is in the liquid state, thereby exhibiting all the properties of a liquid such as:

  • Water flows at this temperature
  • It has a fixed volume and it takes the shape of its container

(b) The melting and boiling points of iron are as high as 1538°C and 2862°C respectively. The room temperature is about 20-25 °C. Hence iron almirah is a solid at room temperature.
