2. Thermodynamics is the study of energy
conversion into heat and mechanical work
DR. C.V. RAMAN UNIVERSITY, KOTA, BILASPUR(C.G.)

3. There are three macroscopic variables which
participate in heat-work conversion cycle
Temperature
Pressure
Volume

4. Heat can never flow from colder body to hotter
body without any external work.
This law is used to determine the performance
limit of heat engine and heat pump.
It give significant informations about all
thermodynamic processes

5. DR. C.V. RAMAN UNIVERSITY, KOTA, BILASPUR(C.G.)
These are the systems that supply or absorb
the finite amount of heat without changing
their temperature

6. Heat engine is the device which converts
heat energy into mechanical work. It
absorbs heat from hot system and eject to
cold system.

7. The thermal efficiency of a heat engine can
never be 100%.
It is not possible to construct an engine which
can convert total heat into mechanical work.
DR. C.V. RAMAN UNIVERSITY, KOTA, BILASPUR(C.G.)

8. It states that entropy of an isolated system
remains unaltered over a period of time.
It is the un-used thermal energy of a
system.
DR. C.V. RAMAN UNIVERSITY, KOTA, BILASPUR(C.G.)

9. Entropy is the degree of disorder of a system.
Thermal energy unavailable for mechanical work
DR. C.V. RAMAN UNIVERSITY, KOTA, BILASPUR(C.G.)

10. It is the base of Heat Engines
It shows limitations of Heat Engines.
It describes the macro-states of the system
