Which substance in the table undergoes the greatest temperature change when the same mass of each substance absorbs the same quantity of heat? Which substance in the table undergoes the greatest temperature change when the same mass of each substance absorbs the same quantity of heat?

CaCO3(s)

CO2(g)

N2(g)

CH4(g)

Al(s)

H2O(l)

Fe(s)

Hg(l)

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
