ose tWO points. nituue of enthalpy a path independent property of a system. That is, the ml path taken ge required to go between two points is the same regardless of the between those two points. SF6 gas molecules will diffuse faster than He gas atoms. The average kinetic energy of SFo gas molecules will be exactly the same as that for He gas molecules as long as both gases are at the same temperature. The average speed of SFo gas molecules will be exactly the same as that for He gas molecules as long as both gases are at the same temperature. d) e) 9. (5 points) True or False a) Equal amounts of heat flowing into 10 grams of aluminum and 10 grams of water will produce the same magnitude of temperature change for both samples. b)--An acceptable set of units for specific heat capacity is (J/g °C) c) If a system's volume increases against an external pressure then the system is doing work on the surroundings. The b term in the Vander Waals real gas equation represents the actual occupied volume of gas particles per mole. d) e)--Water has a larger heat capacity than metals which means water will undergo a larger temperature change for a given quantity of heat absorbed than will a metal. 10. (5 points) For a substance that remains a gas under the conditions listed, the ideal gas law would be followed most closely for: a. 25 °C and 1 atm b. -100 °C and 1 atmExplanation / Answer
9a) if equal amount of heat is flowing into 10grams of metal and water then the temperature change will be same:False
The temperature change depends upon the specific heat of any substance.
b) The unit of specific heat will be J /g 0C: True
c) system' volume increases against an external pressure then the system is doing work on the surrounding :True
d) true: b value represents the actual occupied volume of gas particles per mole
e) If heat capacity is high it means that more amount of energy is required to raise the temperature.
So the given statement is false.
it will undergo lesser temperature change
