Thermodynamics
Introduction to Thermodynamics
Thermodynamics studies heat, work, and energy interactions in systems. It explains energy transfer and transformation, governed by four laws, with applications in engines, refrigerators, and chemical reactions.

Q4. Which of the following best represents a thermodynamic system?
The road and traffic
A car tire
Steam inside a piston-cylinder
A computer program
 Explanation: Steam in a piston-cylinder is a good example of a defined thermodynamic system
5 / 10
Q5. Thermodynamics is NOT concerned with:
Heat interaction
Energy transfer
Work done
Rate of reaction
 Explanation: Rate of reaction is a kinetic concern, not a thermodynamic one.
