The unit of heat is :

1. Watt
2. Joule
3. Calorie
4. Both (2) and (3)

The specific heat capacity of water is:

1. 4200 J kg^-1 K^-1
2. 420 J g^-1 K^-1
3. 0.42 J g^-1 K^-1
4. 4.2 J kg^-1 K^-1

The amount of heat energy contained in a body depends on its :

1. mass
2. temperature
3. material of the body
4. all of the above

The correct relation between heat capacity and specific heat capacity is :

1. C'= m x c
2. C'= 1/mc
3. C'= m/c
4. C = mc'
