Factors affecting rate of evaporation
a) Temperature
Increase in temperature of the liquid enhances evaporation. This is why clothes dry faster on a hot day.
b) Surface area
When the surface area is increased, the molecules of the liquid have greater chance of escaping. Hence a wet cloth would dry faster when it is spread out than when it is folded.
c) Humidity
When there is high amount of water vapour in the atmosphere, it becomes difficult for the molecules to escape.
This is why clothes take longer to dry on a humid day.
d) Draught/moving wind
Moving air above the surface of the liquid sweeps away the escaping molecules. Thus evaporation is enhanced by the passing air.

An aluminium tray of mass 400g containing 300g of water is placed in a refrigerator. After 80 minutes, the
tray is removed and it is found that 60g of water remains unfrozen at 0^oC. If the initial temperature of the tray and its contents was 20^oC, determine the average amount of heat removed per minute by the refrigerator. Take s.h.c of aluminium = 900JKg-1K-1, s.h.c of water = 4200JKg-1K-1, s.l.h. of fusion of ice = 3.4*25JKg

In an experiment to determine the specific heat capacity of a metal, a 20g of the metal was transferred
from boiling water to a lagged copper calorimeter containing cold water. The water was stirred and a
final steady temperature was realized. The following data was recorded:
-initial temperature of cold water and calorimeter =20^oC
-temperature of boiling water =99^oC
-final temperature of water, calorimeter and metal =23.7^oC
-mass of cold water plus calorimeter =130g
mass of calorimeter =50g
Take s.h.c. of water=4200JKg-1K-1, s.h.c. of copper=400JKg-1K-1.
Use the data above to determine:
