Passage IV
A bomb calorimeter is used to determine the amount of heat released when a substance is burned in oxygen (Figure 1). The heat, measured in kilojoules (kJ), is calculated from the change in temperature of the water in the bomb calorimeter. Table 1 shows the amounts of heat released when different foods were burned in a bomb calorimeter. Table 2 shows the amounts of heat released when different amounts of sucrose (table sugar) were burned. Table 3 shows the amounts of heat released when various chemical compounds were burned.
20. According to Tables 1 and 2, as the mass of successive sucrose samples increased, the change in the water temperature produced when the sample was burned most likely:
Your Answer is
Correct Answer is F
Explanation
Look at table 2, as the amount of sucrose increases, the heat released increases;
Look at table 1 again, the greater the heat released, the greater the change in water temperature, so the temperature should rise
