## Homework Statement

Suppose that a tank contains 680 m3 of neon at an absolute pressure of 1.01x105 Pa. The temperature is changed from 293.2 to 294.3 K. What is the increase in the internal energy of the neon? [3.9x105 J]

## Homework Equations

delta Q = delta U + delta W

pV = nRT

## The Attempt at a Solution

there is no potential energy between them. all the kinetic of neon is kinetic since it is ideal gas

how do i find delta Q and delta W. should they be positve or negative?

i assume that an increase in temperature increases kinetic energy. so internal energy increase. delta U is positive?

can you plz tell me how to proceed
