7. It takes 585 J of energy to raise the temperature of 125.6 g mercury from 20.0 degrees C to 53.5 degrees C. Calculate the molar heat capacity of mercury in J/(mol degrees C).
8. The specific heat capacity of silver is 0.24 J/(g x degrees C).
It takes 3.57 kJ of energy to heat a sample of pure silver from 12.0 degrees C to 14.1 degrees C. Calculate the mass of the sample of silver (in kg).
9. The specific heat capacity of silver is 0.240 J/(g x degrees C).
Calculate the energy (in kJ) required to raise the temperature of 263 g Ag from 273K to 278 K.
The problems are to calculate the heat required, specific heat capacities, molar heat capacity and mass of the substance.
These problems are solved using the definition of specific heat capacity.
