To determine the final temperature of each slug, we use the heat equation, where q, the amount of heat, is equal to the heat capacity multiplied by the change in temperature.
00:15
So the change in temperature is simply going to be equal to the heat that we add divided by the heat capacity.
00:23
So in the case of gold, the change in temperature is going to be equal to the heat.
00:31
Heat we add to kilojoules, which is 2 ,000 joules.
00:39
We convert it to joules because our heat capacity has units of joules per degree celsius.
00:45
The gold with a heat capacity of 167 joules per degree celsius.
00:54
So if we divide the 167 joules per degree celsius into 2 ,000 joules, we get 12 ,000.
01:03
0 .0 degrees celsius.
01:08
That is the increase in temperature when we add the heat...
