Question
Luis and Salman are trying to increase the temperature of a substance by heating it. . What is the
quantity of heat in kilojoules required to raise the temperature of 1.2 kg of the substance from3°C
to 110 °C at a pressure of 1.0 atm? Please keep three significant figures.
Useful information: Melting point = 293 K
heat of fusion = 3.90 x 104 J/kg.
boiling point is 423 K
heat of vaporization 7.80 x 104 J/kg (at a pressure of 1.0 atm).
The specific heats for the solid phase is 600 J/(kg K)
The specific heats for the liquid phase is 1000 J/(kg K)
The specific heats for the gaseous phase is 400 J/(kg K)
