Heat Transfer and Weather Review

Karla is boiling water on a stove. When she touches the handle of the pot, she notices it is hot. What is most likely the reason the handle is hot?

• The heat from the stove is carried into the pot’s metal handle through radiation.
• The heat from the stove is carried into the pot’s metal handle through conduction.
• The heat from the stove is carried into the pot’s metal handle through convection.
• The heat from the stove is carried into the pot’s metal handle through transpiration.

Izreal wants to slide down on a sunny day, but the slide is too hot. Which is most likely the reason for the slide being hot?

• radiation from the sun
• convection from the sun
• conduction from the sun
• transpiration from the sun

Which shows an example of convection?

• Levia cooks an egg in a boiling pot of water.

• KaDence burns her hand by touching a light bulb

• Brandy wrapping herself in an electric blanket to keep warm

• Manuel holds the end of a metal rod in fire to cook hot dogs.

Which would be the best way to change a solid to a liquid?

• freeze it
• heat it
• heat it, then freeze it
• freeze it, then heat it

Which best describes the transfer of heat due to the movement of gases or liquids?

• conduction
• radiation
• convection
• insulation

Which is a true statement about heating and cooling water?

• Boiling and freezing water both take an hour.
• It takes less time to boil water than to freeze water into ice.
• It takes less time to freeze water into ice than to boil water.
• It takes the same time to boil water as it does to freeze water into ice.
  

Which is an example of radiation?

• warming food in the microwave

• warming food on the stove

• cooling food in the freezer

Which is an example of convection?

• the heat coming from a campfire

• a spoon in a bowl of soup becoming warmer

• warmer water at the surface of a swimming pool

On a hot summer day, a student dropped an ice cube onto a park bench.

Within minutes, the ice cube melted. Which best describes the process

the student observed?

• radiation

• combustion

• conduction

• condensation

Which is the best choice for the handle of a frying pan?

• Metal, because it conducts heat.

• Wood, because it conducts heat.

• Metal, because it does not conduct heat.

• Wood, because it does not conduct heat.
