In a Carnot engine temperature of the source and sink is 500 K and 375 K. The engine can absorb 600 kcal heat in one cycle. Calculate the efficiency and work done in a cycle.

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

An ideal engine takes in heat at 1000K .and rejects heat 300K . Calculate it's efficiency .

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.

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 .

An ideal heat engine takes in heat at 1520K and rejects heat at 380K . What is the efficiency of that engine ?

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

An ideal gas is taken through the cycle ArarrBrarrCrarrA' as shown. If the net heat suplied to the gas in the cycle is 5J. Calculate the work done by the gas in the process CrarrA'. Give the interpretation of the result.

Assuming that the working substance of a carnot's engine is a perfect gas show that the ratio of heat rejected at the sink to that extracted from the source equals the ratio of absolute temperature of the sink and the source .

One mole of a gas is taken through a cycle as shown in figure calculate. Amount of work done by the gas

Three moles of an ideal gas at a constant temperature of 300 K is compressed from a volume of 4 litres to 1 litre. Calculate the work done in the process. Given R=8.31 Jmol^-1K^-1 .
