Question

The water equivalent of a copper calorimeter is $4.5$ g. If specific heat of copper is $0.09 c a l / g /^{0} C$ , then ( $L_{f} = 80 c a l / g m$ )

Mass of the calorimeter is

0.5

Thermal capacity of the calorimeter is

4.5 c a l^{0} / C

The heat required to raise the temperature of the calorimeter by

8^{0} C

will be

36

cal.

Heat required to melt

15

gm of ice at

0^{o} C

Placed in the calorimeter will be

(A)

m s = 4.5

m \cdot (0.09) = 4.5

m (\frac{9}{100}) = \frac{45}{10}

m = 50 g m = 0.5 k g

(B)

water equivalent

= \frac{m s}{S _{w}}

Heat capacity

= 4.5 \times 1 = 4.5 c a l /^{0} C

(C)

Q = MS Δ T

= 4.5 \times 1 \times 8

= 36 c a l

Hence,

option

(B)

and

(C)

are both correct answer.
