A 130 a gram metal bar requires 2.5 kJ to change its temperature from 27.5°C to 100°C what is the specific heat of the metal

Question

I am taking an online chemistry class and I need help with specific heat of metal questions

Answer 1

Hello Noreen, to find the specific heat of the metal, use the equation q = m Cp delta T, where q=heat energy, m=mass, Cp=specific heat capacity, and delta T=final temp. - initial temp.  Rearranging the equation to solve for Cp, we have Cp = q/(m delta T).  Plug in the values and solve.  You should get 0.27 J/g degrees C.  Please note the units.

 

All the best,
