Thermodynamic variables or parameters:- The thermodynamic state of system can be determined by quantities like temperature (T), volume (V), pressure (P), internal energy (U) etc. In this case, Molar specific heat capacity, at constant volume (, ), is defined as the amount of heat required to raise the temperature of 1 mole of gas through 1º, (b) Specific heat capacity at constant pressure (, Gram molecular specific heat capacity of a gas (, ), at constant pressure, is defined as the amount of heat required to raise the temperature of 1 mole of the gas through 1º. Carnot engine and Carnot's theorem. This signifies that, slope of adiabatic curve is greater than that of isothermal. The distinction between mechanics and thermodynamics is worth noting. THERMODYNAMICS It is the branch of chemistry which deals with the energy changes taking place during physical and chemical changes. In a system that is in equilibrium, no changes in the value of properties occur when it is isolated from its surroundings. This is one of over 2,200 courses on OCW. pressure, volume, mass, temperature, surface area, etc. In particular, it describes how thermal energy is converted to and from other forms of energy and how it affects matter. (a) Isothermal process:- The process in which change in pressure and volume takes place at a constant temperature, is called a isothermal change. Molar specific heat capacity, at constant volume (Cv), is defined as the amount of heat required to raise the temperature of 1 mole of gas through 1ºC keeping its volume constant.

First law of thermodynamics. Reversible and irreversible processes. Let us consider steam as an example to understand the third law of thermodynamics step by step: Whether we are sitting in an air-conditioned room or travelling in any vehicle, the application of thermodynamics is everywhere. The Zeroth law of thermodynamics states that if two bodies are individually in equilibrium with a separate third body, then the first two bodies are also in thermal equilibrium with each other. Basically, this means that if system A is in thermal equilibrium with system C and system B is also in equilibrium with system C, then system A and B are also in thermal equilibrium with each other. When you are in a crowded room with other people you start to feel warm and you start to sweat. Thermodynamics is not concerned about how and at what rate these energy transformations are carried out but is based on initial and final states of a system undergoing the change. Capacity for performing work. The key idea is that materials have "internal energy". Thermodynamics Review. The entropy of the universe only increases and never decreases. According to this law, some heat given to the system is used to change the internal … Property of system which depend only on the state of the system and not on the path.
