Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: Heat, Temperature, and Thermodynamic Systems, Thermodynamic Processes and Equilibrium, Zeroth and First Law of Thermodynamics.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 43 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

4
Day 7

Spaced Revision

Come back to Thermodynamics after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Heat is energy in transit due to temperature difference.
  • Unit of heat: calorie (cal); 1 cal = 4.18 J.
  • Temperature determines the direction of heat flow.
  • Types of systems: open, closed, isolated.
  • Thermodynamic variables: P, V, T.
  • Types of processes: isothermal, adiabatic, isobaric, isochoric.
  • P-V diagram shows pressure vs. volume.
  • Work done = area under the P-V curve.
  • Work is path-dependent, not a state function.

Common Mistakes to Avoid

Heat and temperature are the same thing.

Work done in a thermodynamic process depends only on initial and final volumes.

Internal energy depends only on temperature for all substances.

Memory Tips

Zeroth Law of Thermodynamics: If A = C and B = C, then A = B (thermal equilibrium)

First Law of Thermodynamics: ΔU = ΔQ – ΔW

Sign Convention: Work done BY system is positive, ON system is negative

Adiabatic Process: No heat exchange (ΔQ = 0)
