What is the Required Pressure Difference to Heat 2 Moles of Gas?

[bap902]

Homework Statement

What must the pressure difference be to raise 2 moles of gas at .001 m³ from 12 K to 276 K?

Homework Equations

PV=nRT

The Attempt at a Solution

PV=nRT
P(.001 m³)=(2/6.02x10²³)(8.31)(12)

P(.001 m³)=(2/6.02x10²³)(8.31)(276)

Subtract the two answers to get the difference...

Why are you dividing by Avogadro's number? 'n' in your equations is the number of moles. Just sub in your values, make sure you divide by the volume to find P before you subtract the two pressures.
