FAQs on Maharashtra Board Class 12 Solutions for Physics Chapter 4 Thermodynamics - PDF
1. What happens to the pressure of air in a cylinder if it is compressed using a piston?
If the piston manages to compress the cylinder, heat will be produced, and it will raise the temperature. If the piston is maintaining the same position, the pressure would fall, and there will be a temperature decrease.
2. Why are the laws of thermodynamics important?
The laws of thermodynamics help in defining physical quantities such as temperature, entropy, energy, etc.
3. Describe the foundation of thermodynamics.
The Law of Energy Conservation as well as the observation that heat travels from a hot body to a cold body is the foundation of thermodynamics.
4. Give an example of negative work.
If you are trying to push an object along the floor, the work that is done by the Kinetic Friction would be negative.
5. Is it possible to lose or destroy energy?
No, energy cannot be created nor can it be destroyed. It is only possible to transfer energy from one form to another.
