Question

2. A body absorbs 1000 calories of heat when it is heated from 20°C to 70°C. The water equivalent
of that body is​

Answer 1

Answer:

Heat capacity of the body = 1000/70−20

=20cal/K

Water equivalent is calculated as:

mcw= heat capacity of the body

mcw=20

m×1=20 [cw=1cal/gm−K]

m=20gm

Answer 2

Answer:

heat capacity of the body = 1000/ 70 - 20

water equivalent is calculation : mcw = heat of the body mcw = 20

m×1 = 20 [ CW = 1 cal / gm - k ]

m = 20 gm.
