4.0 g of a gas occupies 22.4 litres at NTP. The specific heat capacity of the gas at constant volume is 5.0 If the speed of sound in this gas at NTP is 952 ms−1, then the heat capacity at constant pressure is (Take gas constant )

What is the difference in temperature of water at the top and bottom of a rainfall of height 500 mts.

(Sp. Heat of water = $$10^3$$​ cal/kg & J = 4.2 J/cal)

The temperature of the reservoir of a Carnot engine, operating with an efficiency of 70% is 1000K. The temperature of its sink is:

The zeroth law of thermodynamics introduces the concept of:

The second law of thermodynamics introduces the concept of:

In an experiment on the specific heat of a metal, a 0.30 kg block of the metal at 120°Cis dropped in a copper calorimeter (of water equivalent 0.025 kg) containing 100 $$\text{cm}^3$$​ ofwater at 27°C. The final temperature is 35°C. Calculate the specific heat of the metal?

A thermacole cubical icebox of side 20 cm has a thickness of 4.0 cm. If 5.0 kg of ice is put in the box, estimate the amount of ice remaining after 5h. The outside temperature is 35°C, and coefficient of thermal conductivity of thermacole is 0.01 J $$\text s^{-1}\space\text m^{-1}\space\text k^{-1}$$​. (Heat of fusion of water = 335 × $$10^3$$​ J $$\text {kg}^{-1}$$​)
