In presentation we saw about carnot engine and carnot cycle, and four process in carnot cycle.

3. • During this process piston of cylinder
Is moved outwards.
• The gas expands at constant
temperature.
• The amount of heat absorbed From
source To make temperature constant.
• Volume increases and Pressure
decreases.
• This is isothermal expansion. That
represented By The curve ab.
1.Isothermal expansion

4. • The piston of cylinder is Moved
outwards
• The gas expands such that No
heat enters or leaves from it.
• Volume increases and pressure
decreases.
• Temperature decreases .
• This is called adiabatic Expansion.
It is represented By the curve BC.
2.Adiabatic Expansion

5. • The piston of cylinder Is Moved Inwards.
• The gas Is compressed At constant
temperature.
• The excess heat produced to maintain
constant temperature.
• Volume decreases, pressure increases.
• This is called isothermal compression.
Represented by curve CD.
3.Isothermal compression

6. 3.Adiabatic compression
• The piston of cylinder Moved
inwards
• The gaS is compressed such that
no heat enters or leaves The
system.
• Volume decreases, pressure
increases.
• Temperature increases.
• This is called adiabatic
compression.represented by the
curve DA.

Where ‘W’is workdone and Q1 is amount of heat
absorbed from source.
