q = (10.0g ? 2.09J/g o C ? 15.0 o C) + (10.0g ? 333J/g)

EXAMPLE: How much heat is required to heat 10.0 g of ice at -15.0 o C to steam at 127.0 o C ? q overall = q ice + q fusion + q water + q boil + q steam. q = (10.0g ? 2.09J/g o C ? 15.0 o C) + (10.0g ? 333J/g) + (10.0g ? 4.18J/g o C ? 100.0 o C) + (10.0g ? 2260J/g)
