Which of the following gases will have the highest velocity at a given temperature?
ne

o2

he

cl2

The velocity of gaseous molecule is dependent on the molecular weight at constant temperature. in this case, ne has a weight of 20.2 g/mol, o2 has 32 g/mol, he has 4 g/mol, cl2 has 70.9 g/mol. the lower the molecular weight, the higher the velocity. among the choices, helium has the highest velocity.

I’m pretty sure it’s false i’m not sure

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
