Which of the following is (are) an endothermic process(es)?- Dilution of sulphuric acid
- Sublimation of dry ice
- Condensation of water vapours
- Evaporation of water
(a) (i) and (iii)
(b) (ii) only
(c) (iii) only
(d) (ii) and (iv)
Correct Answer: (d) (ii) and (iv)
Explanation: Change of solid to gas or liquid to gas absorbs heat hence sublimation of dry ice and evaporation of water is an endothermic reaction.
