if you have 1000g of a substance at -20 degrees celsius with a specific heat of .110 c/1 degree celsius and you add 12 kilojoules to it what is the resulting temperature?

Answer 1

Is that 0.110 cal/g? If so convert that to joules/g
12,000 = 1000 x specific heat x (Tfinal-Tinitial) and solve for Tfinal.Note that Tfinal-Tinitial will become Tfinal+20 because of the sign of the 20.
