00:01
So here they essentially want the volume expansion coefficient for glass.
00:06
So we know that the is going to be equal to 1 ,000 cubic centimeters.
00:24
So we have essentially a glass that is 1 ,000 cubic centimeters and then it's being filled with the metal.
00:33
So we can say that the change in volume will be equal to the original volume, multiplied by the volume expansion coefficient by beta times the change in temperature.
00:43
We can use this for glass.
00:47
So delta vg will be equal to v .0, the original volume times the volume expansion coefficient for glass times delta t.
01:04
And then for metal, for the metal, it'll be equal to v0.
01:20
And so we can say that delta v sub m minus delta v sub g is going to be equal to the volume expansion coefficient sub m minus the volume expansion coefficient sub g times v sub o delta t.
01:40
And so at this point, we know that this is going to be equal to 8 .95...
