Explain about the Heat Extraction?
a) A body of mass M has a temperature-independent precise heat C. If the body is heated reversibly from a temperature Ti to a temperature Tf what is the change in its entropy?
b) Two such bodies are primarily at temperatures of 100 K and 400 K. A reversible engine is used to take out heat with the hotter body as a source and the cooler body as a sink. What is the maximum quantity of heat that can be extracted in units of MC?
c) The specific heat of water is C= 402j/g k and its density is 1g/cm3 Calculate the maximum useful work that can be extracted, using as a source 103 m3 of water at 100°C and a lake of temperature 10°C as a sink.
One of the most important theorems in the quantum physics in the Pauli Exclusion Principle, which is based on the experiment observations. The principle explains that “No two elect
What are slide emitting fibers? No, there are not any side-emitting fibers. All fiber optics acquires the light at one end and transport this to the other. While light enters a
