## Homework Statement

A monatomic ideal gas expands from 1.00 meters cubed to 2.50 meters cubed at a constant pressure of 2.00 x 10^5 Pa. Find the change in the internal energy of the gas.

## Homework Equations

[tex]\Delta[/tex]U = Q + W

## The Attempt at a Solution

Well, I know how to find work, which is -P[tex]\Delta[/tex]V

But I'm having trouble finding the energy transferred into the system by heat, or Q, because the problem does not give a specific value for it.

I would much appreciate it if someone could give me some pointers as to how to find Q.
