Hello, here we have to solve the following problem.
00:03
10 grams of peanuts are burned in a bomb colorimeter, and the heat is completely transferred to water with the mass of half a kilogram.
00:16
And it causes a change of 44 degrees c.
00:23
And we have to determine the heat capacity hue of 33 grams of peanuts.
00:31
So let's solve this problem.
00:32
First of all, let's calculate the ratio of, let's call it r.
00:40
So that is heat capacity of water.
00:43
This is heat of reabsorbed by water divided by initial mass of the peanuts.
00:49
That is mass of water, specific heat capacity of water, delta t, and that is divided by mass of peanuts.
00:56
And therefore, q, which we have to calculate, is this r multiplied by 33 grams.
01:01
In the other words, that is 33 grams over 10 grams times specific heat capacity of water, which is 1 kilocalory per gram degree c.
01:43
That is multiplied by mass of water, which is 500 grams and by increasing temperature...
