00:04
We are given a table full of data and asked to complete the table.
00:15
And i'm going to start writing this.
00:28
And we have first the mass of our metal.
00:34
And this will be in grams.
00:36
Trial 1 is 8 .02, 8 .04 and 8 .02.
00:45
The mass of the cups is 4 .3.
00:57
4 .27 and 4 .28.
01:04
Cup and water is 13 .92, 13 .93, 13 .91.
01:21
13 .91.
01:27
Mass of water will be, i'm gonna call, i'm gonna number these.
01:37
1, 2, 3, 4.
01:42
To get the mass of the cup, from water we're gonna take calculation number 3, minus number two.
01:54
So we have 9 .62, 9 .66, 9 .63.
02:04
Temp of water is 20 degrees c, 22 degrees c, and 21 degrees c.
02:19
Temp of the metal is 100 for all trials.
02:29
I'd get mad of my students if they wrote down just 100, only one significant figure like that.
02:40
My final temp is 28.
03:00
These are my, oops, a dog just came flying to me.
03:04
This is the date i have.
03:06
Then we're asked to find the delta t, delta t for the metal.
03:34
We'll be, where's my 27, will be 100 minus, 10, 106 minus 7.
03:54
That one will be 72 degrees c, 68 degrees c, and 70 degrees c.
04:06
Delta t of our water will be 7 minus 5.
04:22
8 degrees c, 10 degrees c, and 9 degrees c.
04:41
We don't have all the information here.
04:46
Next we have 10 where we're told the delta t for the calorimeter, equals delta t for the water.
05:12
And that's just going to be the 8 degrees c, 10 degrees c, 9 degrees c.
05:18
Our next one says c cal from table one.
05:24
There is no table one.
05:31
So there's no table one.
05:43
You failed.
05:45
No table is provided.
05:48
So this is going to completely screw up every single calculation.
05:54
Because next we're asked to do a cue for the calorimeter, which we don't have...
