I need help setting up this problem and identifying the variables
Energy change is the sum of heat and work: ΔE = q + w. Work is calculated by: w = -PΔV What is the change in energy (in joules) if a reaction loses 215 J of heat and decreases in volume from 0.650 L to 0.225 L at a constant pressure of 3.17 atm? Please include the correct sign with your numerical result.

Could someone show me where I am going wrong in this thermodynamics problem that I got marked wrong? 1 L•atm = 101.325 J A gas expands from 30 L to 50 L against a constant pressure of 1 atm. What is the calculated value for work in Joules? Report your answer in kJ to the nearest whole number. Ok so here is what I did: w = -PΔV w=(50-30)*-1 w=-20 L*atm =101.325*-20 =-2026.5 J =-2.0265 kJ which goes to -2...

Answer . Calculate the internal energy change for each of the following. a. One hundred (100.) joules of work is required to compress a gas. At the same time, the gas releases 23 J of heat. b. A piston is compressed from a volume of 8.30 L to 2.80 L against a constant pressure of 1.90 atm. In the process, there is a heat gain by the system of 350. J. A piston expands against I 1037 J of heat...

Final Answer: 43 125 1. In a steam engine, steam in a cylinder returns to its original state after an expansion/compression cycle. In the expansion step, the volume of the steam increases by exactly 15 L at a constant pressure of exactly 10 atm while 7325 J of 7 heat flows in. In the compression step, the volume of the gas decreases by exactly 15 L at a constant pressure of exactly 15 atm....

part a. The air in an inflated balloon (defined as the system) is warmed over a toaster and absorbs 110 J of heat. As it expands, it does 79 kJ of work. What is the change in internal energy for the system? Express the energy in kilojoules to two significant figures. part b. When fuel is burned in a cylinder equipped with a piston, the volume expands from 0.235 L to 1.350 L against an external pressure of 1.02 atm...
