1. Which mode of heat transfer involves the movement of fluids (liquids or gases)?
Conduction
Convection
Radiation
Absorption
2. What happens when two objects at different temperatures are placed in contact?
Heat flows from the colder object to the hotter object.
Heat flows from the hotter object to the colder object.
No heat transfer occurs.
Both objects increase in temperature.
3. The transfer of heat through direct contact between particles is called .
4. Thermal equilibrium is reached when there is no net of heat between objects.
5. Heat transfer by electromagnetic waves is known as .
6. A vacuum can effectively transfer heat by convection.
True
False
7. Good thermal conductors have loosely bound electrons that can easily move and transfer energy.
True
False
8. Explain the difference between heat and temperature.
9. Describe a real-world example of each type of heat transfer (conduction, convection, and radiation).
10. A metal spoon is placed in a cup of hot coffee. Explain how the spoon eventually reaches thermal equilibrium with the coffee, identifying the primary mode(s) of heat transfer involved. You may use the illustration below to help visualize the scenario.
