1.	1. Explain the Zeroth law of thermodynamics.2. What are the important modes of transference of energy. Explain.
Answer» 1. The Zeroth law of thermodynamics states that if two bodies say, ‘A’ and ‘B’ are in thermal equilibrium with another body say, ‘C’, then the bodies A’ and ‘B’ will also be in thermal equilibrium with each other. It provides the basis for the measurement of temperature. 2. The two important modes of transference of energy are heat and work. Heat: The exchange of energy, which is a result of temperature difference between system and surroundings is called heat (q). Work: The exchange of energy between system and surroundings can occur in the form of work which can be mechanical work, electrical work or pressure-volume work. The exchange of energy as pressure volume work can occur if system consists of gaseous substance and there is a difference of pressure between system and surroundings.
