Molar Specific Heat Of Gas Class 11 [Urdu and Hindi]

The Molar specific heat of a solid or liquid of a material is the heat that you provide to raise the temperature of one mole of solid or liquid through 1K or 1° C. We represent it as C. Its unit is J mol-1K-1. So, to raise the temperature of µ moles of solid through ∆T, you would need an amount of heat equal to ∆Q=µ C ∆T. The molar specific heat capacity of a substance is nothing but the amount of heat you need to provide to raise the temperature of one gram molecule of the substance through one degree centigrade. It is denoted by C. Specific heat of water is taken to be 1. This is because of the reason that we defined unit of heat (calorie) by making use of water. The volume of solid remains constant when heated through a small range of temperature. This is known as specific heat at a constant volume. It is denoted as CV. The pressure of solid remains constant when heated through a small range of temperature. This is known as specific heat at constant pressure which can be denoted as CP. The behavior of gas when heat is supplied, the pressure and volume change in temperature and the amount of heat required to raise the temperature for 1gm of gas through 1°C depends on the way gas is heated. You can use several sets of values of P and V heat the gas. Therefore, specific heat possesses infinite values. The specific heat of the gas is not constant if you do not supply a constant amount of heat. So, you must have specific heat at a constant volume or pressure. For an ideal gas, Cp – CV = nR where CP is heat capacity at constant pressure, CV is heat capacity at constant volume, n is amount of substance, and R=8.3144598(48) J mol−1 K and is the molar gas constant. #BaseAcademyPhysics #11thClassPhysics #NabeelAkhtar #HeatAndThermodynamics Previous Videos: First Law of Thermodynamics 👉   • First Law of Thermodynamics Class 11 Physi...   Isothermal Process and Adiabatic Process in Urdu Hindi 👉   • Isothermal Process and Adiabatic Process i...
