In this question we are given the amount of energy added to a piece of copper.
00:07
We have the mass of that copper.
00:09
We also have the specific heat of copper.
00:12
What we want to know is how many degrees the temperature of the copper is going to change.
00:18
To answer this we need the equation that includes all of these terms.
00:23
Q is the amount of energy that is transferred.
00:26
That is going to be equal to mass times c which is the specific heat times delta t which is the change in temperature.
00:39
So from this question we see that we have 6000 joules of energy are used or transferred to heat up this metal.
00:50
The sample size is just 4 .0 grams.
00:54
The specific heat of copper is 0 .40 joules per gram degrees celsius.
01:04
Delta t is what we are solving for.
01:08
To answer this we just need to divide both sides by 4 .0 grams.
01:16
We have an algebra problem here.
01:18
We are just solving for delta t...
