The second law of thermodynamics introduces the concept of:
The second law of thermodynamics introduces the concept of Entropy.
The second law states that the total entropy of an isolated system always increases over time, or remains constant in a reversible process, making "entropy" the key concept associated with this law.
What is the difference in temperature of water at the top and bottom of a rainfall of height 500 mts.
(Sp. Heat of water = 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 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 . (Heat of fusion of water = 335 × J )
