Explain the operations of a Canot heat engine working between two temperatures and derive its effeciency.

Find the efficiency of a carnot's engine working between 500K and 300K

Find the efficiency of a carnot's engine that works between the temperature 427 degree C and 27 degree C of the source and the sink respectively . If the 140 calories of heat are absorbed from the source by the engine in one cycle calculate the heat rejected into the sink .

What is the difference between heat and temperature?

Calculate the efficiency of a Canot engine operating between 450 K and 300K.

Describe the various operation of a carnot's reversible engine and obtain and expression its efficiency .

Explain the functioning of a photo cell. Give its two uses.

What is the relation between heat and work?

The efficiency of a Carnot engine is frac(1)(6) when temperature if the sink decrease by 65 K its efficiency becomes frac(1)(3) . Calculate the initial and final temperature.

A carnot's engine has an efficiency of 50% when its sinks temperature is 27 degree C what must be the change in its source temperature for increasing its efficiency of 60% ?

The temperature of source and sink of a carnot engine are 400K and 300k respectively its efficiecy is
