Vedclass · Answer

(B) The correct answer is $B$.Internal energy is the sum of all the microscopic energies (kinetic and potential) of the molecules within a system.The $1^{	ext{st}}$ law of thermodynamics is based on the law of conservation of energy and is expressed as:$\Delta Q = \Delta U + \Delta W$Where:$\Delta Q$ is the heat supplied to the system,$\Delta U$ is the change in internal energy of the system,$\Delta W$ is the work done by the system.Rearranging the equation,we get $\Delta U = \Delta Q - \Delta W$. This law provides the definition and quantitative measure of the change in internal energy of a system.

Which of the following laws of thermodynamics defines the term internal energy?
