The change in internal energy of a system (ΔE) can be described in terms of heat (q) and work (w) according to the equation ΔE = q + w. The conversion of 40 g of liquid H2O to steam at 1.0 atm leads to an increase in its volume. This expansion exerts 4.545 kJ of work on the surroundings. If the increase in internal energy of the H2O is 85.724 kJ, how much heat energy does this vaporization process use?...

A piston-cylinder assembly undergoes a cycle consisting of the following three processes: • Process 1-2: Compression with constant internal energy • Process 2-3: Constant-volume cooling to p3 = 100 kPa, V3 = 0.1 m3 • Process 3-1: Constant-pressure expansion with W31 = 12 kJ Sketch the cycle on a p-V diagram, labeling each of the states and indicating the process directions with arrows. If the work for the entire cycle is Wcycle = -20 kJ and changes in kinetic and potential energy are negligible,...

1.) A system absorbs 1.56E+2 kJ of heat and the surroundings do 1.107E+2 kJ of work on the system. What is the change in internal energy (in kJ) (ΔU) of the system? 2.) A sample of gas in a cylinder is provided with 6.221E+2 kJ of heat. This causes a piston to then compresses the gas by doing 4.343E+2 kJ of work to the gas. What is the change in internal energy of the gas during this compression? 3.)A gas...
