Homework Answers

Answer #1

Lower the specific heat of a substance, greater the change in temperature it undergoes

Now, specific heat capacity of CaCO3 = 0.81994 J/g/0C

specific heat capacity of CO2 = 0.844 J/g/0C

specific heat capacity of N2 = 1.04 J/g/0C

specific heat capacity of CH4 = 2.22 J/g/0C

specific heat capacity of Al = 0.9 J/g/0C

specific heat capacity of H2O = 4.186 J/g/0C

specific heat capacity of Fe = 0.45 J/g/0C

specific heat capacity of Hg = 0.14 J/g/0C

Thus, Hg undergoes the greatest temperature change
