The velocity of a 42 kg celestial body reduces from 20 km cdot "min"^(-1) to 5 km cdot "min"^(-1) due to its passage through the earth's atmosphere. Find out the heat produced in calorie. (J = 4.2 xx 10^(7) erg cdot cal^(-1))

A stirrer rotates in 1l of water against a damping force of 0.1 N at 360 rpm in a circle of radius 5 cm. Calculate the rise in water temperature in 1 h, neglecting heat loss due to radiation . (J k= 4.2 J cdot cal^(-1))

If the internal energy U and the work W are expressed in unit of J and the heat is expressed in unit of cal, the first law of thermodynamics will be [here J = Joule's equivalent]

A piece of ice at 0^(@)C is dropped to the ground from some height. The piece of ice melts completely due to its impact with the ground. Find the height from which the piece was dropped considering that 60% of its energy is converted into heat. (J = 4.2 J cdot cal^(-1))

Determine the total kinetic energy of the molecule of 1 g CO_(2) at 27^(@)C in the units of erg and calorie. Assume the ideal behaviour of the gas.
