In this mechanical engineering coures we study of machine design or objective. Q < 0 when the system is at a higher temperature than the environment. The work done by the system or on the system is denoted by ‘w’. 1. Work and heat are highly interrelated but they are not quite the same. You can change your ad preferences anytime. Energy interaction A closed system is interaction with surrounding and another system in 2 way 1) by heat transfer 2) by work transfer Heat transfer. Both heat and work are transient phenomena. Fluid Mechanics one word questions and answers pdf. 2. Both of them are observed at boundaries of the system. If you continue browsing the site, you agree to the use of cookies on this website. these cross the boundaries of system whenever system undergoes a change of state. Heat is the transfer of thermal energy between systems, while work is the transfer of mechanical energy between two systems. This distinction between the microscopic motion (heat) and macroscopic motion (work) is crucial to how thermodynamic processes work. Work: mechanical work is the amount of energy transferred by a force acting through a distance. This indicates the increase in internal energy, i.e., gaining energy by the system by doing work on it. When heat is added, molecules start moving in different directions and thus, the system attains randomness whereas when work is done molecules attain an order.
