A10g piece of metal absorbs 150 joules of heat energy, and its temperature changes from 15° c to 130° c. calculate the specific heat capacity of this metal. predict what metal it is.

You have to use the equation q=mcΔT and solve for c to get c=q/mΔT
q=the amount of energy absorbed or released (in this case 150J)
m= the mass of the sample (in this case 10g)
c=the specific heat capacity of the sample
ΔT=the change in temperature (in this case 115°C)
when you plug everything in you should get 0.1304J/g°C

I hope this helps. Let me know if anything is unclear.
