1) Calculate the change internalenergy (Delta E) for a system that is giving off 32.6 kJ of heatand surroundings are performing 975 J of work on the system.
2) Calculate the change in internalenergy (Delta E) for a system that is giving off 25.0 kJ of heatand is changing from 12.00 L to 6.00 L in volume at 1.50 atmpressure. (Remember that 101.3 J = 1 L?atm)
