Hi there.
00:03
Problem number five wants us to give the equations for some gas laws.
00:09
So letter a is charles law.
00:13
And charles law shows the direct proportion between volume and temperature.
00:22
So charles law, in equation form, is v1 over t1.
00:27
So those are the initial conditions, equals v2 over t2, which are the new conditions.
00:35
Remembering that temperature must be in kelvin.
00:40
For all gas laws, when you're using the equations, temperature must be in kelvin for the equations to work.
00:51
So just a little reminder there.
00:53
All right, moving on to letter b.
00:56
Letter b wants the temperature pressure law, which is gaylu -sac's law.
01:07
Pressure and temperature also have a direct relationship, just like volume and temperature.
01:13
So the equation is going to look similar.
01:15
It's going to be p1 over t1 equals p2 divided by t2, where one is the initial conditions and two are the new conditions.
01:32
So direct proportion...
