So we want to find the relative change in volume for mercury when we increase the temperature from 10 degrees to 28 degrees celsius.
00:10
So we have this expression here that tells us the density of mercury with respect to the temperature.
00:16
So what we're first going to do is we're going to find the density 10 degrees by using this equation.
00:24
So we'll plug in 10 for t here.
00:27
And what we'll end up getting for density is 13 ,000.
00:34
570 kilograms per meters cubed.
00:40
And for the density when the temperature is 20 degrees, we're gonna find that the density will be 13 ,545 kilograms per meters cubed.
00:58
So now we want to find what the relative change in volume will be.
01:01
So we know that we can write the volume in terms of the mass and the density, like so, just mass divided by row...
