During a process, a system absorbs 710 kJ of heat and does 250 J of work. Calculate the change in the internal energy of the system.

Text Solution

AI Generated Solution

To solve the problem, we will use the First Law of Thermodynamics, which states that the change in internal energy (ΔU) of a system is equal to the heat absorbed (Q) by the system plus the work done on the system (W). The formula is given by: \[ \Delta U = Q + W \] ### Step-by-Step Solution: ...
