Question 352

A bowl of liquid is left in a room. Decreasing the temperature of the liquid and increasing the wind speed over the surface of the liquid each change the rate of evaporation.

Which row is correct?

A

Decreasing temperature: rate of evaporation decreases; Increasing wind speed: rate of evaporation decreases

B

Decreasing temperature: rate of evaporation decreases; Increasing wind speed: rate of evaporation increases

C

Decreasing temperature: rate of evaporation increases; Increasing wind speed: rate of evaporation decreases

D

Decreasing temperature: rate of evaporation increases; Increasing wind speed: rate of evaporation increases
