1 Answer. D - Sublimation of dry ice and evaporation of water both are endothermic processes. These processes pull heat (energy) from their surroundings to change from one state to another. ... Dry ice absorbs heat from the environment to convert into gas.

Explanation:

D - Sublimation of dry ice and evaporation of water both are endothermic processes. These processes pull heat (energy) from their surroundings to change from one state to another. Hence both these processes produce cooling rather than heating. Dry ice absorbs heat from the environment to convert into gas. This feature makes it a good refrigerant. Processes of dilution of sulphuric acid and condensation of water vapours produce a large amount of heat. That is why these are exothermic processes.

Some examples are:

Photosynthesis.
Melting ice.
Evaporating liquid water.
Sublimation of carbon dioxide (dry ice)
Cracking of alkanes.
Thermal decomposition reactions.
Electrolytic decomposition of sodium chloride into sodium hydroxide and hydrogen chloride.
Dissolving ammonium chloride in water.
