PS.5.1.3 (5.P.3.1) #3 Schoolnet (Hot to Cold)

Ice cubes are placed in a glass of water that is at room temperature.

Which statement best describes the temperature of the water after 10

minutes?

• The temperature decreases because some of the water’s heat is lost to the ice.

• The temperature decreases because some of the ice’s heat is lost to the water.

• The temperature increases because some of the coolness of the

  water is absorbed by the ice.

• The temperature increases because some of the coolness of the ice

  is absorbed by the water.

Mike is writing a paper about conductors and insulators. Which

statement is most likely to be included in his paper?

• A conductor, such as metal, does not allow heat to pass easily; an

  insulator, such as wood, allows heat to pass easily.

• A conductor, such as metal, allows heat to pass easily; an insulator,

  such as wood, does not allow heat to pass easily.

• A conductor, such as wood, does not allow heat to pass easily; an

  insulator, such as metal, allows heat to pass easily.

How is boiling water an example of convection?

• As the warm water rises, heat energy is transferred from the bottom of the pan to the top, the cool water sinks, and the process repeats.

• As the cool water rises, heat energy is transferred from the top of the pan to the bottom, the cool water then rises, and the process

  repeats.

• As the stove heats the pot, heat energy is transferred from the outside edges of the pot in, then the cool water moves to the edges,

  and the process repeats.

• As the stove heats the pot, heat energy is transferred from the inside of the pot out to the edges, then the cool water moves to the

  center, and the process repeats.

Which best describes the process of heat transfer that allows a hot air

balloon to fly?

• Convection, because the air inside the balloon is heated and as the hot air rises, so does the balloon.

• Conduction, because the air inside the balloon is cooled when it is

  enclosed, causing the balloon to rise.

• Convection, because the air inside the balloon is condensed and as the cool air circulates, the balloon rises.

• Conduction, because the air inside the balloon is warmed, and when it comes in contact with the sides of the balloon, the balloon rises.

Sam burned his fingers on a hot pot. He immediately went to the sink

and ran cold water over the burned fingers. Why is this most likely a

good choice?

• The warmth from the burn will be conducted into the water.

• The coolness from the water will be conducted into the burn.

• The warmth from the burn will be radiated into the water.

• The coolness from the water will be radiated into the burn.

What happens when ice is added to a warm soda?

• The heat transfers from the ice to the soda by conduction, causing the soda to cool.

• The heat transfers from the ice to the soda by radiation, causing the soda to cool.

• The heat transfers from the soda to the ice by conduction, causing the ice to melt.

• The heat transfers from the soda to the ice by radiation, causing the ice to melt.

Which best explains how heat transfers from one object to another?

• Heat always moves from cooler objects to warmer objects.

• Heat always moves from warmer objects to cooler objects.

• Heat always moves from bigger objects to smaller objects.

• Heat always moves from smaller objects to bigger objects.

Gloria put an egg into a pot of water and let the water boil until the egg

was cooked. How was the heat transferred to the egg during this

process?

• Conduction transferred heat from the egg, through the water, and then to the pot.

• Conduction transferred heat from the pot, through the water, and then to the egg.

• Convection transferred heat from the egg, through the water, and then to the pot.

• Convection transferred heat from the pot, through the water, and then to the egg.
