Solution
The correct option is D Freezing
The explanation for Correct answer
(d) Freezing
- The process in which a liquid changes into its solid state at a constant temperature by releasing heat is called freezing.
- The constant temperature at which the liquid changes into its solid state is known as the freezing point.
- The freezing point of water is 0°c, which means water changes into ice when the temperature reaches 0°c.
The explanation for incorrect answer
(a) Boiling - It is the process in which liquid changes into a gaseous state by absorbing heat. Example: boiling of water
(b) Melting - It is the process in which solid changes into a liquid state by absorbing heat. Example: melting of ice cream.
(c) Condensation - It is the process in which gas changes into a liquid. Example: dew drops, fog.
Therefore, freezing is the process in which water changes into ice.
