A vertical cylinder fitted with a frictionless piston contains carbon dioxide. The mass and cross-sectional area of the piston are 50 kg and 250 cm2, respectively. The atmospheric pressure outside of the container is 100 kPa and the local acceleration gravity is 9.8 m/s2. a) What is the carbon dioxide pressure inside the cylinder if the piston is at rest? (Answer: 1.2105 Pa) b) If some heat is transferred to the gas and its volume doubles, do you expect the pressure inside the cylinder to change?
