Why is whitewash sometimes applied to the glass of florists' greenhouses? Would you expect this practice to be more prevalent in winter or summer months?
To explain: If whitewash is applied to the glass of florists’ greenhouse in summer or winter months.
Explanation of Solution
Introduction:
White colors are good reflectors and hence poor absorbers of heat and light.
Since a greenhouse is transparent, sunlight can pass through it. Too much sunlight during summer months are not good for the flowers. Whitewash reflects sunlight and hence reduces incoming radiant energy, which is good for the flowers.
Conclusion:
Whitewash is applied to the glass of florists’ greenhouse in summer months to reflect excess sunlight.
