For many purposes we can treat propane (C3H₂) as an ideal gas at temperatures above its boiling point of -42. °C. Suppose the temperature of a sample of propane gas is lowered from 24.0 °C to -18.0 °C, and at the same time the pressure is changed. If the initial pressure was 7.1 atm and the volume increased by 45.0%, what is the final pressure? Round your answer to the correct number of significant digits. atm X S

For many purposes we can treat nitrogen (N₂) as an ideal gas at temperatures above its boiling point of -196. °C. Suppose the temperature of a sample of nitrogen gas is raised from -84.0 °C to -65.0 °C, and at the same time the pressure is decreased by 5.0%. Does the volume of the sample increase, decrease, or stay the same? O increase decrease O stays the same If you said the volume increases or decreases, calculate the percentage change in % the volume. Round your answer to the nearest percent. □ x10 X

For many purposes we can treat nitrogen (N2) as an ideal gas at temperatures above its boiling point of −196.°C. Suppose the temperature of a sample of nitrogen gas is lowered from16.0°C⁢ to −12.0°C, and at the same time the pressure is changed. If the initial pressure was 3.1atm and the volume increased by 35.0%, what is the final pressure? Round your answer to 2 significant digits

A sample of krypton at 38.5 °C had a pressure of 0.710 atm. When the pressure changed to 0.851 atm at 68.2 °C, the volume was 325.0 mL. Calculate the original volume (mL).
