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.

 Explanation: Thermodynamics deals with the transformation and transfer of heat and energy.
9 / 10
Q5. Thermodynamics is NOT concerned with:
Heat interaction
Energy transfer
Rate of reaction
Work done
 Explanation: Rate of reaction is a kinetic concern, not a thermodynamic one.
10 / 10
Q2. Which of the following is a primary concern of thermodynamics?
Material strength
Mechanical vibrations
Energy conversion
Fluid flow
 Explanation: Thermodynamics focuses on how energy is converted from one form to another.
