If a thermodynamic system is perfectly conducting to surroundings and undergoes a physical change in such a way that temperature remains constant throughout, then process is said to be isothermal process. 207, Laxmideep Building Plot No. According to law of conservation of energy the total energy change in the universe is constant however it can be converted from one form to another. temperature T is constant and work done is, Since, T = constant so for ideal gas dU = 0. In cyclic process the work done is equal to area under the cycle and is -ive if cycle is anti-clockwise and +ive if cycle is clockwise (shown in fig. Two systems are said to be in thermal equilibrium with each other if they have the same temperature. It is the branch of chemistry which deals with the energy changes taking place during physical and chemical changes. In contrast, a quantity that has only magnitude and no direction, such as temperature or time, is called a scalar. CBSE Class 11 Physics Notes : Thermodynamics. Revision Notes on Thermodynamics.
