Answer 1

Let's go through the questions one by one:

**Question 5:** Which substance has the most energy?
- **Answer:** a. olive oil
(Olive oil, being a substance with a higher potential energy due to its chemical bonds, typically has more energy compared to iron, brick, or water.)

**Question 6:** Which way does the energy flow when heat is added to the iron and the brick?
- **Answer:** a. from the heater to the brick and iron
(Heat flows from the heater to the objects being heated.)

**Question 7:** As you added heat, what happened to the temperature of the brick and iron?
- **Answer:** a. the temperature increased
(When heat is added to substances, their temperatures typically increase.)

**Question 8:** Which way does the energy flow when cooling the brick and iron?
- **Answer:** b. from the brick and iron to the ice
(Energy flows from the warmer objects (brick and iron) to the cooler object (ice).)

**Question 9:** As you cooled the brick and iron, what happened to their temperatures?
- **Answer:** c. the temperature decreased
(When heat is removed from a substance, its temperature typically decreases.)
