Review-Heat Transfer and Earth's Resources

What is the primary method by which heat is transferred from the Sun to the Earth?

• Conduction

• Convection

• Radiation

When you touch a hot pot, the heat transfer that causes your hand to feel hot is an example of:

• Convection

• Conduction

• Radiation

Two cups, Cup X and Cup Y, are filled with hot coffee. Cup X is made of ceramic, while Cup Y is made of plastic. Which cup will keep the coffee hot for a longer period? Why?

• Cup X, because ceramic is a better insulator than plastic

• Cup X, because ceramic is a better conductor than plastic

• Cup Y, because plastic is a better insulator than ceramic

• Cup Y, because plastic is a better conductor than ceramic

When water freezes into ice, it releases heat from __________ to __________.

• Warmer temperature to cooler temperature

• Cooler temperature to warmer temperature

• The same temperature to the same temperature

• The inside environment to the outside environment

How does convection differ from conduction in terms of heat transfer mechanisms?

• Convection requires direct contact between objects, whereas conduction does not.

• Conduction transfers heat through a fluid due to the movement of the fluid itself, while convection transfers heat through direct contact.

• Conduction involves the transfer of heat through direct contact, while convection relies on the rising and falling of fluids or gasses.

• Both conduction and convection require electromagnetic fields to transfer heat.

In an experiment, a Bunsen burner is used to heat a flask containing oil. The movement of oil shows the pattern of heat flow. What is the main method of heat transfer observed in this scenario?

• Conduction

• Convection

• Radiation

• Condensation

During a cold night, how does the warmth from a campfire reach the campers sitting around it?

• Conduction

• Convection

• Radiation

Why does the attic of a house tend to be hotter than the basement during summer?

• Conduction

• Convection

• Radiation

What defines a resource as being renewable?

• Renewable resources can be replenished or replaced relatively quickly through natural processes.
• Renewable resources take a long time to replenish
• Renewable resources are not affected by human activity
• Renewable resources are only available in limited quantities

Which of the following is considered a renewable resource?

• Solar Energy

• Coal

• Natural Gas

• Petroleum
