Question
Read the following statements. Which of the following statements are incorrect? (i) Onheating, water from oceans changes into vapours. (ii) Salts dissolved in the oceans areleft behind after evaporation of water by sunlight. (iii) Evaporation of water does not takeplace under the shade. (iv) The hot surface of glass containing boiled water cools the airaround it. (v) Water in the form of ice goes into air by fusion and transpiration.A. (i) & (ii) onlyB. (ii), (iii) & (v)C. (iii) & (v) onlyD. (iii) (iv) & (v)
Solution
The incorrect statements are (iii) Evaporation of water does not take place under the shade. and (iv) The hot surface of glass containing boiled water cools the air around it.
Statement (iii) is incorrect because evaporation can occur in any conditions where there is water present, not just in direct sunlight. It may be slower in the shade, but it still occurs.
Statement (iv) is incorrect because a hot surface will heat the air around it, not cool it.
So, the answer is D. (iii) (iv) & (v). Statement (v) is also incorrect because ice does not go into air by fusion and transpiration. Fusion is a process of changing state from solid to liquid and transpiration is a process in plants, not related to ice melting.
