In an experiment to determine the enthalpy of combustion of an alcohol, the mass of a burner plus its contents, and the temperature of a known mass of water in a calorimeter are measured before and after the experiment. What are the expected results?
a. Mass of burner and contents: decreases, Reading on thermometer: increases
b. Mass of burner and contents: decreases, Reading on thermometer: stays the same
c. Mass of burner and contents: increases, Reading on thermometer: increases
d. Mass of burner and contents: increases, Reading on thermometer: stays the same
