First of all...thanks for any help. This is ultrabasic introduction to therm, so I know everyone says that no question is stupid, but I just feel like I'm really missing the boat here.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

The temperature of a monatomic ideal gas remains constant during a process in which 4390 J of heat flows out of the gas. How much work (including the proper + or - sign) is done on the gas?

2. Relevant equations

[tex]\Delta[/tex]E=nCv[tex]\Delta[/tex]T

and I think...maybe

[tex]\Delta[/tex]E=Q - W

3. The attempt at a solution

Since it says that the temperature remains constant, I was thinking that [tex]\Delta[/tex]E=0

Q is the heat supplied TO the system, so if 4390 J of heat came out, then it would be -Q.

So I figured that:

[tex]\Delta[/tex]E=Q - W

0=-4390 - W

W=-4390 Joules

That's not correct. They must be telling me that it's a monatomic ideal gas for some reason.

HELP!!
