Asked by Amanda
A substance has the following properties:
Heat capacities:
1.34 J/g oC (solid)
3.02 J/g oC (liquid)
2.55 J/g oC (gas)
Heat of Fusion = 4.23 kJ/mole
Heat of Vaporization = 23.5 kJ/mole
Boiling Point = 88.5 oC
Melting Point = -30.0 oC
Molar Mass = 96.3 g/mole
How much energy (in kJ) would be needed to heat 55.5 g of this substance from -39.0 to -15.0oC?
