Okay, a 48 .3 milliliter sample of gas in a cylinder is warm from 22 degrees celsius to 87 degrees celsius.
00:08
What's the volume at the final temperature? so what we want to do in this problem is use what's something called boyle's law.
00:17
No, not boyle's law, which relates volume to temperature.
00:23
This is what boils law.
00:25
Charles law, what i keep saying, boyle, charles law is.
00:29
It is the idea that volume and temperature are proportional.
00:36
But for this to work, we have to make sure that we're not in celsius.
00:42
We're in kelvin.
00:47
Okay.
00:49
So if we have this original volume of 48 .3 milliliters, and this original temperature of 22 degrees celsius, we're slowly.
01:05
Solving for the final temperature, right? that's our unknown, final volume, sorry.
01:10
And the final temperature is 87 degrees celsius.
01:16
So first, let's convert these temperatures.
01:19
See how celsius to kelvin is just adding 273 .15.
01:29
So the first temperature is actually going to be, we can do this in our heads, 295 .15 kelvin.
01:43
If we add it here, then we're going to get, pull out my calculator to make sure i don't make any silly mistakes here.
01:56
You get t2 equals 360 .15.
02:01
Okay, now we have all of our givens...
