PS.5.1.3 (5.P.3.1) #2: Schoolnet (Hot to Cold)

A student places a cup of cold water on a counter in a hot room. After a short time, the student notices that the water in the cup is no longer cold. Which best explains why the water in the cup is no longer cold?

• The coldness of the water transferred to the air, making the water in the cup warmer.

• The coldness of the water was conducted to the cup, making the water in the cup

  warmer.

• The heat from the air transferred to the water in the cup, making the water in the cup

  warmer.

• The heat from the air caused the cold water in the cup to condense, making the

  water warmer.

James measured the temperature outside his house everyday for 2

months. He observed that on days the sky was mostly cloudy, the

temperature was an average of 9 degrees cooler than days the sky was

mostly sunny. Which best describes the reason for this pattern?

• The clouds blocked radiation from the sun, causing cooler

  temperatures.

• The clouds blocked conduction from the sun, causing cooler

  temperatures.

• The clouds allowed more radiation from the sun to reach the Earth’s

  surface.

• The clouds allowed more conduction from the sun to reach the Earth’s

  surface.

Jordan places a hot spoon into a container of ice cream. How does this

help him scoop out the ice cream?

• The coolness from the ice cream is conducted to the spoon making it

  easier to scoop out.

• The coolness from the ice cream is radiated to the spoon making it

  easier to scoop out.

• The warmth of the spoon is conducted to the ice cream making it easier to scoop out.

• The warmth of the spoon is radiated to the ice cream making it easier

  to scoop out.

Tom puts a metallic cover over his car’s windshield after parking. How

does this control the sun’s rays during a sunny day?

• It prevents heat energy from leaving the car.

• It controls the temperature by providing shade.

• It reflects the sun’s rays away from the windshield.

• It absorbs heat in the windshield protector and cools the car.

Which best explains why a hot air balloon floats?

• The heated air expands to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.

• The heated air expands to fill the balloon. The air in the balloon is now heavier than the surrounding air, causing the balloon to rise.

• The heated air contracts to fill the balloon. The air in the balloon is now denser than the surrounding air, causing the balloon to rise.

• The heated air contracts to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.
