Hi, so we are calculating the final temperature of copper based on the given information here.
00:07
So the equation that we're going to use is the formula for heat for change in temperature.
00:11
So q is equivalent to mass multiplied by the specific heat capacity and then the change in temperature.
00:17
For heat is equivalent to mass, the specific heat, and then delta t is final temperature minus the initial temperature.
00:24
So rearranging this one, the final temperature of copper is for equivalent to heat divided by mass of the sample, specific heat of copper plus the initial temperature.
00:37
So let's plug in the given information, the amount of heat or energy here is 84 joules over the mass of the sample 4 .50 grams.
00:47
Specific heat of copper is 0 .38 joules per gram kelvin and then the initial temperature is 25 degrees celsius.
00:58
We need to convert this to kelvin, we'll add 273 .15...
