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
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]]
