Which of the following are exothermic processes?- The reaction of water with quick lime
- Dilution of an acid
- Evaporation of water
- Sublimation of camphor (crystals)
(a) (i) and (ii)
(b) (ii) and (iii)
(c) (i) and (iv)
(d) (iii) and (iv)
Correct Answer: (a) (i) and (ii)
Explanation: During exothermic processes, an enormous amount of heat is released. When water reacts with quick lime and acid reacts with water an enormous amount of heat is released. Hence, it is an exothermic process.
