example of conduction 21-22 Test 2 -

Which is an example of conduction?

• Steam is rising from a cup of hot coffee.

• A hot biscuit is warming the plate it is on.

• The sun is shining through a window and warming a table.

Which best explains why a pan placed on a hot stove top will begin to warm?

• conduction

• convection

• radiation

Joe is cooking dinner on the stove. When he picks up the pan by the handle, he burns his hand. Which form of heat transfer caused Joe to burn his hand?

• radiation

• conduction

• convection

Jill notices that her skin gets burned when she sits out in the sun. What best explains why his happens?

• The soil is convecting heat into the air.

• The heat from the sun is being conducted to the Earth.

• The heat from the sun is radiating down to Earth's surface.

Which is the best example of radiation?

• warming hot dogs over a fire

• boiling water on a stove-top burner

• burning a piece of paper with a candle flame

Which best describes the process of conduction?

• When two objects touch, the heat is transferred into the air.

• When two objects touch, the heat from the hotter object is transferred to the cooler object.

• When two objects touch, the cool air from the cooler object is transferred to the hotter object.

Which part of the diagram shows conduction?

• Part A

• Part B

• Part C

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

Tina is boiling water in a metal pot for a weather experiment. What is most likely the reason she would need to use a pot holder for moving the metal pot?

• Radiation causes the pot to be hot.

• Conduction causes the pot to be hot.

• Convection causes the pot to be hot.

• Transpiration causes the pot to be hot.

A cold metal spoon is placed in a bowl of hot soup. Which best describes how the spoon is affected?

• The heat from the soup does not affect the temperature of the spoon.

• The heat from the soup is conducted through the spoon, making the spoon warmer.

• The cold air in the room radiates into the soup, cooling it, and keeping the spoon cool.

• The cold from the spoon is conducted into the soup, causing the soup to cool to the same temperature as the spoon.
