ACT Practice Science P4

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:

• Increased only
• Decreased only
• Increased, then decreased
• Stays the same

Which of the following graphs best illustrates the relationship between the heat released by the foods listed in Table 1 and the change in water temperature?

• A
• B
• C
• D

Based on the data in Table 2, one can conclude that when the mass of sucrose is decreased by one-half, the amount of heat released when it is burned in a bomb calorimeter will:

• Increase by one-half
• Decrease by one-half
• Increase by one-fourth
• Decrease by one-fourth

Which of the following lists the foods from Tables 1 and 2 in increasing order of the amount of heat released per gram of food?

• Potato, egg, bread, sucrose, cheese
• Sucrose, cheese, bread, egg, potato
• Bread, cheese, egg, potato, sucrose
• Sucrose, potato, egg, bread, cheese

Based on the information in Tables 1 and 2, the heat released from the burning of 5.0 g of potato in a bomb calorimeter would be closest to which of the following?

• 5 kJ
• 10 kJ
• 15 kJ
• 20 kJ
