Answer 1

HI

IN CASE ONE
EVAPORATION WILL BE FASTER IN CHINA DISH
THERE ARE 3 FACTORS AFFECTING EVAPORATION

1)WIND SPEED:
IF WIND IS MORE RATE OF EVAPORATION INCREASES
AND VICE VERSA

2)SURFACE AREA:
IF SURFACE AREA IS MORE RATE OF EVAPORATION INCREASES
AND VICE VERSA

3)HUMIDITY:
HUMIDITY IS WATER VAPOUR PRESENT IN ATMOSPHERE
IF HUMIDITY INCREASES EVAPORATION
DECREASES AND VICE VERSA

SO IN CASE 1
EVAPORATION WILL BE LESS AS COMPARED TO SUNNY AND WINDY DAY
