Five moles of a monatomic ideal gas expand adiabatically, and its temperature decreases from 410 to 200 K.
(a) What is the work done by (or done to) the gas? Include the algebraic sign.
(b) What is the change in the internal energy of the gas? Include the algebraic sign.
a. w = _ 13094,55 b. e = _ 13094,55
