This document is a presentation on the laws of thermodynamics given by Jay Shah, Stanley Chisty, and Rutvik Shah to their classmates. It introduces the first law of thermodynamics as the law of conservation of energy, and provides examples of cycling and melting ice. The second law is summarized as entropy always increasing over time for isolated systems. Examples given are heat transfer from hot to cold. The zeroth law is stated as if A=C and B=C then A=B in thermal equilibrium. An example of tea, coffee, and the environment is also provided.

1. GOOD MORNING
RESPECTED TEACHER
AND
MY DEAR FRIENDS

2. GUJARAT
TECHNOLOGICAL
UNIVERSITY

4. PRESENTED BY:
-> JAY SHAH
-> STANLEY CHISTY
-> RUTVIK SHAH
GUIDED BY:
-> Prof. Dhruv Joshi

5. Our topics for ALA presentation
1) First Law Of Thermodynamics
2) Second Law Of Thermodynamics
3) Zeroth Law

6. FIRST LAW OF THERMODYNAMICS
-> The energy can neither be created nor can
be destroyed but can be converted into one
form from another.
-> This law is also known as Law Of
Conservation Of Energy.

7. EXAMPLES BASED ON THE FIRST LAW OF
THERMODYNAMICS:
-> Cycling

8. -> Melting of an ice

9. SECOND LAW OF THERMODYNAMICS
-> The second law of thermodynamics states that
the total entropy of an isolated system always
increases over time, or remains constant in ideal
cases where the system is in a steady state or
undergoing a reversible process.

10. EXAMPLES BASED ON THE SECOND LAW
OF THERMODYNAMICS
-> Thermal energy flow from higher
temperature to lower temperature.

11. ZEROTH LAW
-> If body A and body B are in thermal
equilibrium with body C, then body A and
body B has to be in thermal equilibrium with
each other.

12. EXAMPLES BASED ON ZEROTH LAW
-> If the temperature of tea A and also the
temperature of coffee C is in thermal equilibrium
with the temperature of environment B, then the
temperatures of tea A and coffee C are in thermal
equilibrium.
