What is thermodynamics?
Thermodynamics is the study of heat, work, energy, temperature, and the laws governing energy conversion.
What are the four laws of thermodynamics?
They are the zeroth law of thermal equilibrium, the first law of energy conservation, the second law of entropy increase, and the third law concerning absolute zero.
What is the difference between heat and work?
Heat is energy transferred because of a temperature difference, while work is energy transferred by forces or organized processes.
What does the first law of thermodynamics state?
It states that energy is conserved: changes in a system’s internal energy equal heat added to it minus work done by it.
What is entropy in thermodynamics?
Entropy is a measure of energy dispersal and the number of possible microscopic arrangements in a system.
How does statistical thermodynamics relate to thermodynamics?
Statistical thermodynamics explains macroscopic properties such as temperature, pressure, and entropy using the behavior of particles.
What is thermal efficiency in a heat engine?
Thermal efficiency is the fraction of heat input converted into useful work, with the remainder released as waste heat.
