Calculate the work performed by an ideal carnot engine as a cold brick warms from 150 k to the temperature of the environment, which is 300 k. (use 300 k as the temperature of the hot reservoir of the engine). the heat capacity of the brick is c = 1 kj/k.

To solve this problem, apply the concepts related to the calculation of the work performed according to the temperature change (in an ideal Carnot cycle), for which you have to:

Where,

C = Heat capacity of the Brick

= Cold Temperature

= Hot Temperature

Integrating,

Our values are given as

Replacing,

Therefore the work perfomed by this ideal carnot engine is 58kJ

wavelength divides in half and speed stays the same.
