Question

Given 13.5 grams of substance Z, if the substance absorbs 36 kilojoules of energy and the temperature increases by 25 degrees Celsius, what is the specific heat of the substance?

Answer 1

Hey and welcome to OpenStudy!
I guess we are after the specific heat capacity.
You know the relation for the specific heat capacity?

Answer 2

I do not

Answer 3

Okay, then I give you the relation.
\[\large \Delta U = m ~ C _{m} ~ \Delta T\]
Here are:
\(\Delta U\) the change in energy.
\(m\) the mass of the compound.
\(C_{m}\) the specific heat capacity
\(\Delta T\) the change in temperature.
Try solve for \(C_{m}\) for me please :)

Answer 4

Or let me do it for you:
\[\large C _{m}=\frac{ \Delta U }{ m ~ \Delta T }\]
Just set into the equation and calculate \(C_{m}\). Should not be a problem.

Answer 5

This is an old post, but this helped me greatly for my homework. I couldn't find this relation formula anywhere in my course!

Answer 6

Only glad it could help! :)
