# How much heat is exhausted to the cold reservoir by the heat engine shown in ?

The heat exhausted to the cold reservoir by heat engine,

See the step by step solution

## Step: 1 Definition of heat transfer in cold reservoirs:

(a) Heat moves spontaneously from a hot to a cold item, according to the second rule of thermodynamics.

(b) A heat engine, shown as a circle, operates by utilising some of the heat transmission. The hot and cold things are the heat and cold reservoirs.

## Step: 2 Finding the value of :

We can find the lost heat as

Heat taken from the heat reservoir,,will be equal tothe sum of the heat taken in the two processes.That is,

## Step: 3 Finding the value of :

The work finish on the gas will be same to the space encircled by the graph. Since this is the triangle, we have

Finally, the heat lost to the cold reservoir is
