The specific heat of co2 (

g. is 0.840 j/g °c and the specific heat of caco3 (

g. is 0.820 j/g °

c. if 1.00 gram of each substance starts at the same temperature and absorbs 1.00 x 102 j of heat. what would be the difference between their final temperatures?

Heat gained or lost by a system is calculated by the product of mass, specific heat and the difference in the temperature of a process. We can calculate the final temperatures of the systems above as follows:

H = mC (Tf-Ti)

CO2

100 = 1 (0.840) (Tf - 273.15)

tf = 392.20 K

CaCO3

100 = 1 (0.820) (Tf - 273.15)

Tf = 395.10 K

There is about 2 degrees celsius difference.
