The weight of a person if 60 kg. If he gets 10⁵ calories heat through food and the efficiency of his body is 28%, then upto how much height he can climb (approximately)

The thermal capacity of a body is 80 cal, then its water equivalent is

A vessel contains 110 g of water. The heat capacity of the vessel is equal to 1 g water. The initial temperature of water in vessel is 10^oC. If 220 g of hot water at 70^oC is poured in the vessel, the final temperature neglecting loss, will be

A hailstone at 0^oC falls from a height of 1 km on an insulting surface converting whole of its kinetic energy into heat. What part of it will melt? (g = 10 m/s²)

The SI unit of mechanical equivalent of heat is

If two masses of 5 kg each falling from height of 10 m, by which 2 kg water is stirred. The rise in temperature of water will be

A lead ball moving with a velocity v strikes a wall and stops. If 5% of its energy is converted into heat, then what will be the increase in temperature(specific heat of lead is S)?

A mechanical equivalent of heat J is

Boiling water is changing into steam. At this stage the specific heat of water is

A block of mass 100 g slides on a rough horizontal surface. If the speed of the block decreases from 10 m/s to 5 m/s, the thermal energy developed in the process is
