#### Adiabatic, reversible process on ideal gas

An ideal gas with constant specific heats, c_{v} and c_{p},
is compressed adiabatically and reversibly.

- Which property of the ideal gas remains constant during this
particular process ?

- Prove that for this process the initial state (index 1) and final state
(2) are related by the equation :
p
_{1} v_{1}^{n} =
p_{2} v_{2}^{n}
HINT : use an equation for the property given as answer to question 1.

- Express the exponent "n" in terms of the specific heats
c
_{v} and c_{p}.
