Extracted text: 1. A sample containing 1.0 mole of oxygen gas initially at 45 degrees Celsius is heated to 110 degrees Celsius under isobaric conditions. From these given data, answer the questions that follow. a) What is the sample's change in internal energy (in kilojoules)? Write answer in three significant figures. b) What is the sample's change in enthalpy (in KiloJoules)? Write answer in three significant figures. c) Assuming that the accurate Cp value for oxygen gas can be obtained from the relationship given below, what would be the sample's new change in enthalpy (in KiloJoules)? Write answer in three significant figures. Cp°02 25.72 + 12.98 x10-3 T - 38.60 x10-7 T² %3D
