pressure remains constant that the balloon occupies one leader of
volume at room temperature what's its volume when cooled by
the liquid nitrogen and hear the financial answer I'm leaving
This experiment calls for the ideal gas law thiss law
explains how an ideal gas will act We assume that
being ideal in all it'll keep its room clean and
always be polite No wait That's not right And i
feel guest is a hypothetical gas that will always act
predictably Formula for an ideal gas law is pv equals
and katie this thing in this glacier p is pressure
be is volume and is the number of molecules Hey
sabi is bosman's constant and he is the temperature in
kelvin because it's the coolest Okay now that we have
that jan di door brains let's take another look at
our experiment Remember we're dropping a bullet gets a liquid
nitrogen because that's our idea of fun on a friday
night judges the balloon is sealed so the amount of
particles and pressure remain the same And remember we're trying
to figure out how the change in temperature effects the
change in volume Let's look at the two equations from
different volumes Since we're solving for volume we'll just rearrange
the equations by dividing both sides By p we could
dividing rearrange the equations canceling out everything but the volumes
And the temps visa two equals t's up to over
t someone times visa of one lycan in the Numbers
We have 77 degrees kelvin over three hundred reason calvin
times one leader which means the volume is about equal
to a point two five leaders and that makes me
the correct answer Well so there we have it Now
we can go fun playing around with liquid nitrogen and
just remember to wear gloves No one wants to end 00:02:00.643 --> [endTime] up with a hand sickle Well
