Hi, so to solve for this, we'll equate the amount of heat lost and then the amount of heat gained by the water.
00:07
So heat lost by metal is equivalent to the amount of heat gained by water.
00:19
And this will be negative since this is heat lost.
00:22
Negative mass, specific heat, and then a change in temperature.
00:26
This is for the metal.
00:28
And on the right side, we have positive mass, specific heat, change in temperature for water so let's rearrange this equation to solve for the specific heat capacity of metal.
00:40
We'll have positive mass of water, change in temperature and the specific heat capacity over negative mass and then the change in temperature.
00:52
This is for the metal.
00:54
Okay, so let's plug in the information that we have.
01:00
The mass of water is 100 grams.
01:04
The specific heat capacity is 4 .184 joules per gram degree celsius.
01:11
And then the change in temperature, the final temperature is 22 .3 degrees celsius minus the initial temperature of water sample.
01:18
That's 20 degrees celsius.
01:22
Sorry, that's right.

The unit outside the parentheses over mass of metal...
