What is the specific heat of copper if a 105 g sample absorbs 15200 joules and the change in temperature is 377 0C ? (Draw a temperature time graph)

Answer : The specific heat of copper is,

Explanation :

Formula used :

where,

q = heat absorb = 15200 J

m = mass of sample = 105 g

c = specific heat capacity of copper = ?

= change in temperature =

Now put all the given values in the above formula, we get:

Therefore, the specific heat of copper is,

It's 23.14 percent

Explanation:

First, the mass of all the elements are:

N = 14

O = 16

Fe = 56

In this molecule you have 3 atoms of N, and 9 atoms of O, so:

3•14 = 42

16•9 = 144

The whole mass of the molecule is:

56 + 42 + 144 = 242

242/100 = 2.42, so 1% is 2.42

56/2.42 = 23.14%
