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.
See sample questions for grade 12
A gas expands adiabatically and does 400 J of work. What is the change in internal energy of the gas?
A gas expands isobarically from 2 L to 5 L at a constant pressure of 100 kPa. Calculate the work done by the gas.
A gas is compressed isothermally. What happens to the entropy of the gas?
A gas undergoes an adiabatic expansion. What happens to its internal energy?
A system absorbs 500 J of heat and does 200 J of work on the surroundings. What is the change in internal energy of the system?
Calculate the change in internal energy for 2 moles of an ideal gas heated from 300 K to 400 K at constant volume. (Assume C_v = 3R)
Calculate the work done by an ideal gas during an isothermal expansion from volume V₁ to V₂ at temperature T. (Use n for moles and R for gas constant.)
Describe what happens to the pressure and temperature of an ideal gas during a free expansion (expansion into vacuum).
During an isothermal expansion of an ideal gas, what happens to the internal energy of the gas?
During which thermodynamic process does the temperature of an ideal gas remain constant?
Explain the difference between reversible and irreversible thermodynamic processes.
Explain why no work is done during an isochoric process.
Explain why the temperature of a gas changes during an adiabatic process but not during an isothermal process.
If a process is both isothermal and adiabatic, what can you say about the system?
In a PV diagram, what does a vertical line represent?
State the condition for a process to be called quasi-static.
State the first law of thermodynamics.
What is the mathematical condition for an isothermal process for an ideal gas?
