Which statement is always true if ΔU sys is always negative?

a) q = w
b) +q>–w
c) -w> +q
d) +w>-q

1. delta U = heat in - work out
delta U = Q - W in physics
HOWEVER chem texts sometimes use
delta U = Q + W
with W = work IN so maybe that is what you have here.
in that case if delta U is - then
Q < -W heat in less than work out which is c)
