CALORIMETRY

The water equivalent of a copper calorimeter is 4.5g. If specific heat of copper is .09 cal /g/°c, then:-
(1) Mass of the calorimeter is .5 kg

(2) Thermal capacity of the colorimeter is 4.5 cal /° C

(3) The heat required to raise the temperature of the calorimeter by 8° C will be 36 cal.

(4) Heat required to melt 15 gm of ice placed in the colorimeter will be 1200 cal

CHOSE THE CORRECT OPTION FROM BELOW

(A) 1 is correct (B) 2,3 only are correct

(C) 2,3,4 are correct (D) 3,4 only are correct

yes option C is correct .

2) is definition

3) Q= 4.5*8=36 cal

4) temp. change =0

heat absorbed by calorimeter is zero.

Q= mL= 15*80= 1200 cal

1.wrong as mass is 50g
2.wrong coz of wrong units
3.correct but no option saying only 3
4.WRONG COZ depends on temperature of ice![may be it is below freezing point..........ooo so cold!![3]]
