Correct option is B Thermal capacity of the calorimeter is 4.5cal 0 /C C The heat required to raise the temperature of the calorimeter by 8 0 C will be 36 cal. (A) ms=4.5 m⋅(0.09)=4.5 m( 100 9 )= 10 45
m=50gm=0.5kg (B)water equivalent = S w
ms
Heat capacity=4.5×1=4.5cal/ 0 C (C) Q=MSΔT =4.5×1×8 =36cal Hence, option (B) and (C) are both correct answer.
Correct option is
B
Thermal capacity of the calorimeter is 4.5cal
0
/C
C
