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 is compressed adiabatically and its temperature rises. Explain why.
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 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 system undergoes a cyclic process. If the total work done by the system is 400 J, what is the net heat absorbed?
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.
A gas undergoes an isochoric heating process. Which of the following quantities changes? (1) Pressure, (2) Volume, (3) Work done, (4) Number of moles
During which process is the heat supplied to the system entirely used to increase its internal energy? (1) Isobaric, (2) Isochoric, (3) Isothermal, (4) Adiabatic
In a PV diagram, which process is represented by a horizontal line? (1) Isothermal, (2) Isochoric, (3) Isobaric, (4) Adiabatic

During an adiabatic expansion of an ideal gas, the temperature of the gas ________.
During an isothermal compression, the heat supplied to the gas is ________ the work done by the gas.
In an isochoric process, the work done by the gas is ________.
In an isothermal process, the change in internal energy (ΔU) of an ideal gas is ________.
True or False: In a cyclic process, the net change in internal energy of the system is zero.
True or False: In an adiabatic process, the temperature of an ideal gas always increases.
True or False: In an adiabatic process, there is no heat exchange between the system and its surroundings.
True or False: In an isobaric process, the heat supplied to the system is partly used to do work and partly to increase internal energy.
