Question

A gas is allowed to expand, at constant temperature, from a volume of 1.0 L to 10.0 L against an external pressure of 0.50 atm. If the gas absorbs 250 J of heat from the surroundings, what are the values of q, w, and delta E?

Answer 1

is delta e internal energy?

Answer 2

\[q=\Delta U + w\]

Answer 3

I don't know about the delta E. :(

Answer 4

What is delta U?

Answer 5

enthalpy

Answer 6

\[w=\int\limits_{V_i}^{V_f}PdV\]

Answer 7

\[w=nRT \ln \frac{V_f}{V_i}\]

Answer 8

alright so delta u = zero and w=-q
