O GASES, LIQUIDS, AND SOLIDS Using the combined gas law For many purposes we can treat methane (CH4) as an ideal gas at temperatures above its boiling point of -161. °C. Suppose the temperature of a sample of methane gas is raised from - 12.0°C to 15.0 °C, and at the same time the pressure is changed. If the initial pressure was 6.8 atm and the volume increased by 35.0%, what is the final pressure? Round your answer to 2...
O GASES, LIQUIDS, AND SOLIDS Calculating enthalpy of vaporization from vapor pressure The vapor pressure of Substance X is measured at several temperatures: temperature vapor pressure 0.0799 atm 17. °C 32. °C 0.120 atm 0.172 atm 47. °C Use this information to calculate the enthalpy of vaporization of X. Round your answer to 2 significant digits. Be sure your answer contains a correct unit symbol. II
