How much heat is required to heat 1.0 10³ kg (a metric ton) of aluminum from room temperature (25C) to its melting point (660.C)?

How much heat must be supplied to 41 g of ice at -28C to convert it to steam at 154C? (Specific heats: ice = 2.0 J/gC; water = 4.2 J/gC; steam = 2.0 J/gC. Molar heat of fusion of water at 273 K = 6.01 kJ/mol. Molar heat of vaporization of water at 373 K = 40.7 kJ/mol.)

Mercury has the following physical properties: normal melting point = -39C, normal boiling point = 357C, heat of fusion = 2.33 kJ/mol, heat of vaporization = 284 J/g, specific heat = 0.139 J/gC. Calculate H for the conversion of 159 g of solid mercury at its freezing point to mercury vapor at its boiling point.

A 0.195 mole sample of solid NaX is dissolved in 275 mL of water in an insulated container at 23.7C After the solid dissolves, the temperature of the water is 19.2C. What is the heat of solution of NaX?
