Question

The temperature of a piece of copper with a mass of 95.4g increases from 25 degrees Celsius to 48.0 degrees Celsius when the metal absorbs 849 J of heat. What is the specific heat capacity of copper?

Answer 1

Answer:

The answer is 3.87 J/gC

Answer 2

Answer:

The answer is 3.87 J/g°C

Explanation:

Here is the equation we are going to use:

$C=\frac{q}{mT}$

C= specfic heat in J/g°C

q = heat in joules (J)

m = mass in grams (g)

T = change in temperature

Here is what is given:

q = 849 J

m = 95.4 g

T = 48.0 - 25.0 = 23°C

Find:

Specific heat capacity in J/g

The first thing we are going to do is plug everything into the equation:

$C = \frac{849J}{(9.54g)(23degreesC)}$

Then we are going to solve for C

$C = \frac{849J}{219.42gC} = 3.87 J/gCelsius$

Hope this helps!
