Which of the following combination of factors do not affect evaporation? (i) Temperature (ii) Nature of liquid exposed (iii) Impurities (iv) Pressure (v) Humidity (vi) Draught (vii) linear expansivity (viii) electro negativity
A. vii and viii B. i, ii, iii C. iii, iv, v, vi D. i, ii, iii, iv, v
Correct Answer: A
Explanation
Linear expansivity and electronegativity do not affect evaporation.vaporation is the change of state of a liquid into its vapour at any temperature. It is a surface phenomenon i.c. it occurs at the surface. As evaporation occurs, the temperature of substances falls, so we say evaporation causes cooling.vaporation is affected by the factors listed except linear expansivity and electronegativity.
