Question

Use the slider to add heat to the iron and the brick and pay close attention to the energy symbols.

Which way does the energy flow?

a
energy does not flow
b
from the brick and iron to the heater
c
from the heater to the brick and iron
Question 7
As you added heat, what happened to the temperature of the brick and iron? (Hint: Use the thermometer)

a
the temperature increased
b
the temperature decreased
c
the temperature did not change
Question 8
Use the slider to cool the brick and the iron, and pay close attention to the energy symbols.

Which way does the energy flow?

a
from the brick and iron to the ice
b
energy does not flow
c
from the ice to the brick and iron
Question 9
As you cooled the brick and iron, what happened to their temperatures? (Hint: Use the thermometer)

a
the temperature does not change
b
the temperature decreased
c
the temperature increased

Answer 1

Here are the answers to your questions based on the given scenarios with heat transfer:

**Question 6**: Which way does the energy flow when heat is added to the iron and the brick?
- **Answer**: c) from the heater to the brick and iron

**Question 7**: As you added heat, what happened to the temperature of the brick and iron?
- **Answer**: a) the temperature increased

**Question 8**: When you use the slider to cool the brick and the iron, which way does the energy flow?
- **Answer**: a) from the brick and iron to the ice

**Question 9**: As you cooled the brick and iron, what happened to their temperatures?
- **Answer**: b) the temperature decreased

These answers reflect the basic principles of heat transfer – energy flows from hotter objects to cooler ones, resulting in temperature changes accordingly.
