FAQs on Short Tricks: Thermodynamics Video Lecture - Chemistry for JEE Main & Advanced
| 1. What is the first law of thermodynamics? |  |
Ans. The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted from one form to another.
| 2. How does the second law of thermodynamics differ from the first law? | |
Ans. The second law of thermodynamics states that the entropy of an isolated system will always increase over time, leading to a decrease in the system's ability to do work. This is in contrast to the first law, which focuses on the conservation of energy.
| 3. Can you explain the concept of heat transfer in thermodynamics? | |
Ans. Heat transfer in thermodynamics refers to the process of thermal energy moving from one substance to another due to a temperature difference. This can occur through conduction, convection, or radiation.
| 4. What is an adiabatic process in thermodynamics? | |
Ans. An adiabatic process in thermodynamics is one in which there is no heat exchange with the surroundings. This means that the change in internal energy of the system is equal to the work done on or by the system.
| 5. How is the efficiency of a heat engine calculated in thermodynamics? | |
Ans. The efficiency of a heat engine is calculated by dividing the work output of the engine by the heat input to the engine. This ratio gives a measure of how effectively the engine converts heat into useful work.
