Use energy equation to solve the following:
4. How much heat is required to raise the temperature of 854 g of H2O from 23.5 °C to 85.0 °C?
5. Phosphorus trichloride, PCI3, is a compound used in the manufacture of pesticides and gasoline
additives. How much heat is required to raise the temperature of 96.7 g PCl3 from 31.7 °C to 69.2 °C?
The specific heat of PCI3 is 0.874 J/g°C.
Carbon Tetrachloride, CCI4, was a very popular organic solvent until it was found to be toxic. What is
the specific heat of the solvent if 2154 J of energy is required to raise the temperature of 103.5 g of
Cl4 from 32.1 °C to 56.4 °C.
