6. Describe what is happening to both the poreitial energy mid the chorage kinerie energn of the tolecules in the amorid sample during rime internal BC. Town response must include both porential energy and average Antetic energy:
7. Caleulate the total hear absorbed by the 5,00-gram sample of ammonia during time interval AB.
Your response must include bork a correct mumerical setup and the calculated result.
S. Base your answer to the following question on the following paragraph.
The boiling point of a quid is the temperature at which the rapor pressure of the liquid is equal to the pressure on the surface of the liquid. The hen of vaporization of ethanol is 838
joules per gram. A sample of ethanol has a mass of 65.0 grams and is boiling at 1.00 afmosphere.
Calculate the mininun amount of heat required to completely vaporize this sample of ethanol.
Your response must include both a correct numerical setup and the calculated result.
