a) The refractive index of glass.
?g= velocity of light in vacuum/velocity of light in glass= (3.0*28)/( 8.0*28) =1.50
b) The angle of refraction in glass for a ray of light incident at the air-glass interface at an angle of incidence of
400.
Sin 400/sin r =1.50
r=sin-1(sin40/1.50)= 10.40.

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.
