a.Determine the amount of energy to raise the temperature of 18 kg of carbon from -5^0C to 17^0C.(adsbygoogle = window.adsbygoogle || []).push({});

B. 200g of a certain substance absorbs 7320 J of energy and experienced a temperature rise from 5^0C to 30^0C. By calcuating its "C" value, identify as near as possible, the unknown substance.

delta t= 17-5=12^0C. M=18kg

C=709j/kg

energy=cXmXdelta t

709J/kg.K X 18kg X12K

energy=3.28 KJ

=3.3 X10^2?

Im not sure what im doing. Need help
