## Homework Statement

twenty moles of a monatomic ideal gas (lambda=5/3) undergo an adiabatic process the initial pressure is 400kpa and the initial temperature is 450K. The final temperature of the gas is 320K.

The heat absorbed by the gas in kJ is closest to?

a.0

b.+54

c.+32

d.-54

e.-32

## Homework Equations

Q=0

## The Attempt at a Solution

I think this is suppose to be a trick question. I thought an adiabatic process ment zero heat was gained or lost. Therefore shouldn't the answer be zero regardless of the temperature, moles, or pressure values given?
