in this example, the surroundings are doing work on the system, so the sign of the work term is negative. the equation can be interpreted as E = Q - (-)W = Q + W
I cannot understand something.. From question (a) for total work is negative so I think it may be work done by gas but you write work done on gas... From question (b) E=q+w...why minus sign before w?if we use that we get from (a) negative w then why again use negative magnitude in calculation again... thankful if reply. #@AK LECTURES
From going to point 2 to point 3 when the volume remains the same, the system's internal energy increases since energy is added to the system as heat, but what kind of isovolumetric process would this be? Is there a such thing as isovolumetric expansion and isovolumetric compression, or is it named something else?
Love this channel, thank you so much
why did you change the equation delt E= Q-W from delt E=Q+W???

U have just saved my grade ;)
Awesome! Thanks!
