We're given the following information.
00:03
I have a silver block, and this is my unknown.
00:12
This is what i have to find.
00:17
And my silver block, my temperature initial for my silver block, is 57 .7 degrees celsius.
00:27
We submerge this in water with a mass of 100 .0 grams at a temperature of 24 .9 degrees celsius.
00:42
The final temperature, and that'll build for both, is equal to 26 .9 degrees celsius.
01:01
The heat capacity for silver is 0 .235 j over g degrees c, and my heat capacity for my water, specific heat is 4 .18 j over g degrees c.
01:26
We are asked to suppress to two significant figures, two figs and units.
01:41
We know that the cue of the silver is going to equal the heat of the water and we know that both cues will be calculated calculated using mass times c times the change of temperature.
02:03
My change of temperature for these two temperatures, subtracting those two values, will be 57 .7 minus 26 .9, 30 .8 degrees.
02:26
And my temperature for these two, would be 26 .9 minus 24.
02:38
Is 2 .0.
02:45
So those are my two changes of temperature.
02:50
Let's get started.
02:51
Mass of silver is unknown...
