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.

Q3. Thermodynamics is based on:
Theories without observation
Mathematical assumptions only
Experimental laws
Chemical equations
 Explanation: Thermodynamic laws are derived from consistent experimental observations.

Q10. Which of the following best defines thermodynamics?
Study of natural laws only
Study of energy and its interactions with matter
Study of stars and planets
Study of living organisms
 Explanation: Thermodynamics is fundamentally about energy, heat, and their relation with matter.
4 / 10
Q2. Which of the following is a primary concern of thermodynamics?
Material strength
Energy conversion
Fluid flow
Mechanical vibrations
 Explanation: Thermodynamics focuses on how energy is converted from one form to another.
5 / 10
Q5. Thermodynamics is NOT concerned with:
Energy transfer
Rate of reaction
Work done
Heat interaction
 Explanation: Rate of reaction is a kinetic concern, not a thermodynamic one.
