Isochoric Process Quiz: Test Your Knowledge with Answers

📚 Quick Study Guide

🔍 Definition: An isochoric process is a thermodynamic process during which the volume remains constant. Also known as a constant-volume process or an isometric process. 🌡️ Volume: $\Delta V = 0$ ⚙️ Work Done: Since volume is constant, no work is done by or on the system: $W = 0$ 💡 First Law of Thermodynamics: The change in internal energy is equal to the heat added to the system: $\Delta U = Q$ 🧮 Ideal Gas Law (Isochoric):$\frac{P}{T} = constant$ or $\frac{P_1}{T_1} = \frac{P_2}{T_2}$ ⚡️ Application: Heating a gas in a closed, rigid container is a common example.
