Hello! can someone please explain this question....
Which statement is false?
a) Kr has a lower average speed than Ne at the same temperature.
b) The molecules of a gas undergo many collisions with each other and with the walls of the container
c) Deviations from the ideal gas law are greater at low temperature and high pressue
d) All molecules of an ideal gas have the same kinetic energy at constant temperature
e) All are true
so:
a) Kr: 84: heavier; Ne:20: Faster == True
b) True
c) Ideal gases work at its best in High Temps and Low Pressure== True
d) I thought Kinetic energy is directly proportional to temperature, so as long as both gases are at the same temperature they should share the same kinetic energy, right???
I chose E, but destroyer says that D is false.... How is this? Is this a mistake on destroyer? or am I missing something??? From watching Chad's videos he literally says that if 2 atoms have the same temperature, then they will both have the same kinetic energy but different speeds...
Thank You!!🙂
