WebFirst law of thermodynamics. The first law of thermodynamics is explained as “The total change in internal energy of a system is the sum of the heat added to it and the work … WebThe first law asserts that if heat is recognized as a form of energy, then the total energy of a system plus its surroundings is conserved; in other words, the total energy of the universe remains constant. The first law is put into action by considering the flow of energy across the boundary separating a system from its surroundings.

Webe. The laws of thermodynamics are a set of scientific laws which define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium. The laws also use various parameters for thermodynamic processes, such as thermodynamic work and heat, and … WebSolution. An adiabatic process is a process during which there is no transfer of heat from or to the system. For adiabatic change, Q = 0. ∴ ΔU + W = 0. ∴ ΔU = –W. This implies, for adiabatic expansion, W is positive and ΔU is negative i.e. when work is done by the system adiabatically its internal energy decreases.
