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.

    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?...

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...

    help on 1a and b please 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....

    I need help with these two 1 The table below shows time, temperature, and temperature change data collected using Pivot Lab#8 (Specific Heat of Water Experiments). The heat supplied, Q, is to be calculated from Q = Pt (where P is the power of the light bulb which is 25 watts and t is the time). For example, when t = 200 s, Q = 25 watts x 200 s = 5000 Joules. Plot Temp. Change (vertical axis) versus Heat...

    A piston containing 0.75 moles of a perfect gas at 25 degrees C is moved isothermally from a starting volume of 8.305 L. Calculate the work in joules if the piston is moved irreversibly against a constant external pressure of 4.100 atm. We weren't giving final volume so I am unsure of what to do. I tried to use P1V1 = P2V2 because the final pressure is equal to external pressure in an irreversible process. But then my final volume...
