Preparing for the MDCAT Physics section can feel challenging, especially when students need to balance theory, formulas, and numerical problem-solving. Among all the topics, Chapter 5: Thermodynamics is considered one of the most crucial. This chapter explains the fundamental principles of heat, work, energy, and the laws of thermodynamics—concepts that are not only vital in Physics but also form the foundation of medical and biological processes.
To help MDCAT aspirants, we provide a chapter-wise MCQ test with answers for Thermodynamics. By practicing these questions, students can evaluate their preparation, master key formulas, and improve time management for the final exam.
Importance of Thermodynamics in MDCAT Physics
The MDCAT Physics syllabus allocates significant weightage to Thermodynamics. On average, 4–5 MCQs appear from this chapter, making it essential for securing higher marks. The questions are usually a blend of conceptual understanding and numerical application, so candidates need to strengthen both areas.
- 📌 Difficulty Level: Moderate to High
- 📌 Question Types: Laws of thermodynamics, heat transfer, internal energy, entropy, efficiency of engines, and specific heat capacities.
- 📌 Scoring Potential: High (if formulas are practiced well)

Important Formulas for MDCAT Thermodynamics
Here are the key formulas every MDCAT aspirant should memorize for Thermodynamics:
- First Law of Thermodynamics: ΔU = Q – W
- Work in isothermal process: W = nRT ln(Vf/Vi)
- Work in adiabatic process: W = (PfVf – PiVi) / (γ – 1)
- Efficiency of Carnot engine: η = 1 – (Tc/Th)
- Heat capacity relation: Cp – Cv = R
- Entropy change: ΔS = Qrev / T
- Heat transfer equation: Q = mcΔT
👉 Pro Tip: Always remember the units and dimensions while solving numerical problems, as MDCAT often includes unit-based tricky questions.
