The thermal expansion in three dimensions is given by delta v, that's changed in volume, is equal to beta times v.

V times delta t.

And the thermal volume coefficient of expansion of ethyl alcohol, that's beta ethyl, let's write down e for ethyl, that is equal to 1100 multiplied by 10 ,000 ,000 ,000 ,000 ,000, to the power minus 6 per degree centigrade right now to calculate the change in volume of the ethyl alcohol we substitute the values of beta right and then the volume and change in temperature so change in volume of ethyl is equal to 1100 multiply by 10 to the power minus 6 multiply by 500 multiply by change in temperature, that's 22 minus 5 and that is equal to 9 .35.

Well, the thermal volume coefficient of expansion of glass, beta, g, let's write on g from glass, is equal to 27 times 10 to the power minus 6 per degree, centigrade, and now let us find out change in volume of the glass well change in volume the glass is equal to 27 multiply by 10 to the power minus 6 let's say it's a thermal coefficient of expansion multiply by 500 into change in temperature well change in temperature is 22 minus 5 right so change in of glass is equal to 0 .2295.

Alright, okay.

Now, then the amount of ethyl alcohol that will overflow will be equal to difference between these changes of volume...
