Question

What are the four processes of a Carnot heat engine?

Answer 1

Answer:

Carnot engine have four processes , two are constant temperature and other two are reversible adiabatic processes.

Explanation:

Carnot heat engine :

   Carnot heat engine is an ideal heat engine in which all processes are reversible processes it means that when process is reversed then it does not leave any effect on the system and surrounding.

Carnot heat engine have four process,out four two are constant temperature processes(1&2,3&4) and other two are reversible adiabatic processes(4&1,2&3).

The efficiency of Carnot heat engine given as follows

$\eta =1-\dfrac{T_L}{T_H}$

Answer 2

Answer:

Carnot engine have four processes , two are constant temperature and other two are reversible adiabatic processes.
