Water Cycle and Heat Transfer Review

A pot is heated on a stove. Which process causes the metal handle ofthe pot to also become hot?

• combustion
• convection
• radiation
• conduction

A dark colored wall becomes warm when the Sun is shining on it. After the Sun sets, a person standing a meter away can feel warmth from the wall. How does heat transfer from the wall tothe person?

• radiation
• conduction
• convection
• insulation

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

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 cupwarmer.
• 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 thewater warmer.

What is the original source of most of the energy that people use?

• Energy that reaches Earth’s surface by radiation from the Sun.
• Energy that reaches Earth’s surface by convection from the Sun.
• Energy that reaches Earth’s surface by radiation from Earth’s core.
• Energy that reaches Earth’s surface by conduction from Earth’s core.

What conditions are necessary for heat conduction to occur between two objects?

• The objects must be surrounded by air or water.
• Two objects at different temperatures are touching one another.
• Two objects at different temperatures are located close to one another.
• One object must emit energy as light and heat and another object absorbs the energy.
