A Quantity of Carbon Monoxide Gas Is Slowly Compressed Adiabatically

question 17

Multiple Choice

A quantity of carbon monoxide gas is slowly compressed adiabatically in an insulated container to one-half of its initial volume. The ratio of the specific heat capacities at constant pressure and constant volume, c_P/c_V , for carbon dioxide is approximately 1.3. Determine the final pressure of the gas if the initial pressure is 2.0 × 10⁵ Pa.

• A)2.0 × 10⁵ Pa
• B)2.6 × 10⁵ Pa
• C)3.7 × 10⁵ Pa
• D)4.9 × 10⁵ Pa
• E)5.2 × 10⁵ Pa
