Another option to substitute gasoline is methanol (CH3OH, which is used in certain high-performance vehicles. To design engines that will run on methanol, we must understand its thermochemistry. [first part of question] The methanol in an automobile engine must be in the gas phase before it can react. Calculate the heat (in kilojoules) that must be added to 1.00 kg liquid methanol to increase its temperature from 25.0°C to its normal boiling point, 65.0°C. The molar heat capacity of liquid methanol is 81.6 J/ K mol . Once the methanol has reached its boiling point, it must be vaporized. The molar enthalpy of vaporization for methanol is 38 kJ/ mol . How much heat must be added to vaporize 1.00 kg methanol?
