26. You have a 4.00 mole sample of the compound. a. What temperature does this sample melt at? b. How much heat is required to melt this sample? c. What temperature does this sample boil at? How much heat is required to boil this sample? d. e. How much heat is required heat the sample in the liquid phase from Tm to Tb? f. What is the total amount of heat that is required to heat a solid at the melting temperature to a liquid at the boiling temperature? g. What is the total amount of heat that is required to heat a solid at the melting temperature to a gas at the boiling temperature? h. Parts f and g both end at the same temperature. Why don't they require the same amount of heat? d. Calculate the amount of heat that would be required to heat a 10 g sample of water by 10 K. Do this calculation for each phase. e. Does it matter what phase water is in when determining how much energy is required to heat a sample?
