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 10
A gas is heated at constant pressure. What type of thermodynamic process is this?
Define an isobaric process.
Describe what happens to the internal energy of an ideal gas during an isochoric process when heat is supplied.
During which thermodynamic process does the internal energy of an ideal gas change only due to work done, with no heat exchange?
A gas is compressed at constant temperature from 4 L to 2 L. If the initial pressure is 1 atm, what is the final pressure? (Assume ideal gas behavior.)
A gas is compressed at constant volume. What is the work done by the gas?
A gas is heated at constant pressure from 2 L to 5 L. If the pressure is 1 atm, calculate the work done by the gas.
