Thermodynamic Processes
Physics ⇒ Heat and Thermodynamics
Thermodynamic Processes starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Thermodynamic Processes.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

A gas expands adiabatically and does 150 J of work. How much heat is exchanged with the surroundings?
A gas is compressed adiabatically and its temperature rises. Explain why.
A gas is compressed at constant pressure from 5 L to 2 L. If the pressure is 100 kPa, calculate the work done on the gas.
A gas is compressed isothermally. What happens to its internal energy?
A gas is heated at constant pressure. What happens to its volume?
A gas is heated at constant volume. What is the work done by the gas?
A system undergoes a cyclic process. If the total work done by the system is 400 J, what is the net heat absorbed?
Define an isochoric process.
During an isobaric expansion, a gas absorbs 600 J of heat and does 400 J of work. What is the change in internal energy?
During an isothermal expansion, the work done by an ideal gas is given by W = nRT ln(Vf/Vi). If n = 1 mol, R = 8.314 J/(mol·K), T = 300 K, Vi = 10 L, and Vf = 20 L, calculate the work done.
Explain the difference between reversible and irreversible thermodynamic processes.
Explain why no heat is transferred in an adiabatic process.
Explain why the work done in an isothermal expansion of an ideal gas is greater than that in an adiabatic expansion for the same initial and final volumes.
If a system absorbs 500 J of heat and does 200 J of work, what is the change in its internal energy?
If a system does 100 J of work and loses 50 J of heat, what is the change in internal energy?
State the first law of thermodynamics.
State the mathematical expression for work done during an isobaric process.
