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 absorbs 72.8 J of heat and increases in volume from 0.250L to 0.750L at a constant pressure of 1.168 atm? Please include the correct sign with your numerical result.
(Note: Make sure your units are consistent when combining energy terms. The conversion factor you need is: 1 L·atm = 101.3 J)
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?...
Calculate the change in internal energy (ΔE) for a system that is giving off 25.0 kJ of heat and is changing from 12.00 L to 6.00 L in volume at 1.50 atm pressure. (Remember that 101.3 J = 1 L • atm)

400 J of heat is added to a system. If the change in internal energy of the system was 850 J, how much work was done on by the system? the inside a container absorbs 250 J of hea while 125 J of work is done on it and then does 70 J of its own work, by how much does the internal energy of the gas increase? 7.500 joules of heat is added to a system while it also...
