Numerical problems usually revolve around P-V diagrams.<\/div>\n<\/details>\n\n<details>\n<summary>Why is the work done in an isochoric process zero?<\/summary>\n<div class=\"faq-answer\">Work done is given by W = P\u0394V. In an isochoric process, volume is constant, meaning \u0394V = 0, thus W = 0.<\/div>\n<\/details>\n\n<details>\n<summary>How do intensive and extensive variables differ?<\/summary>\n<div class=\"faq-answer\">Intensive variables like pressure and temperature do not change with the amount of matter. Extensive variables like volume and total energy scale with the system size.<\/div>\n<\/details>\n\n<details>\n<summary>What is the significance of \u03b3 (gamma)?<\/summary>\n<div class=\"faq-answer\">Gamma (\u03b3) is the ratio of Cp to Cv. it determines the slope of adiabatic curves and the speed of sound in gases.<\/div>\n<\/details>\n\n<details>\n<summary>Can a heat engine have 100% efficiency?<\/summary>\n<div class=\"faq-answer\">No. According to the Second Law of Thermodynamics (Kelvin-Planck statement), some heat must always be rejected to a sink at a lower temperature.<\/div>\n<\/details>\n\n<div class=\"internal-links\">\n<span>Related Study Resources<\/span>\n<a href=\"https:\/\/ksquareinstitute.in\/blog\/neet-physics-survival-kit-2026\/\">NEET Physics Survival Kit 2026<\/a>\n<a href=\"https:\/\/ksquareinstitute.in\/blog\/organic-chemistry-strategy-neet\/\">Organic Chemistry Strategy<\/a>\n<a href=\"https:\/\/ksquareinstitute.in\/blog\/neet-biology-tricks-for-exams\/\">Biology Tricks for Exams<\/a>\n<\/div>\n\n<\/div>\n\n<div class=\"cta-section\">\n<h2>Ready to Crack NEET Physics?<\/h2>\n<p>Mastering Thermodynamics is just the beginning.
