Solution

The correct options are
B Thermal capacity of the calorimeter is 4.5 calC1.
C Heat required to raise the temperature of the calorimeter by 8C will be 36 cal
D Heat required to melt 15 gm of ice placed in the calorimeter will be 1200 cal
W=(msSω)4.5=m×0.091
m=4.50.09=50 g=0.05 kg
(b) Thermal capacity = ms
=4.5×1 calC1=4.5 calC1
(c)Q=msΔT=4.5×8 cal=36 cal
(d)Q=mL=15×80=1200 cal
Why this question?

Basic definition of water equivalent and thermal capacity. JEE asks questions on these basic definitions.
