EOG Prep #1

Mrs. Taylor places a hot spoon into a container of

ice cream. How does this help her 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.

Ms. Miles put a heat pack on her cold feet. What will most likely be the result?

• The cold from Ms. Miles’s feet will be radiated into the heat pack.

• The warmth of the heat pack will be radiated onto

  Ms. Mile’s feet.

• The cold from Ms. Miles’s feet will be conducted into the heat pack.

• The warmth of the heat pack will be conducted onto Ms. Miles’s feet.

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.

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.

Ms. Baker puts a metallic windshield cover over her car’s windshield after parking. How does this best 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 cover and cools

  the car.

Which best explains how bacon is fried on a stove burner?

• The bacon creates a convection current, the heat

  rises to the pan, and then rises to the stove

  burner.

• The bacon transfers heat directly to the pan, and

  the pan radiates heat to the bacon.

• The stove burner radiates heat to the pan, and

  the pan radiates heat to the bacon.

• The stove burner conducts heat to the pan, and

  the pan conducts heat to the bacon.

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.

People sitting around a campfire are able to feel the

heat from the fire. How are the people best able to feel the heat from the fire without touching the fire?

• The heat from the fire travels through the ground

  and heats the ground around the people.

• The heat from the fire is conducted through air molecules to the people.

• The heat from the fire rises in the air and then settles around the people.

• The heat from the fire radiates from the fire to the people.

Justin was sunburned at the beach, and her mother applied lotion to the burn. Why did this make her sunburn feel better?

• The coolness from the lotion was conducted into

  the burn.

• The coolness from the lotion was radiated into

  the burn.

• The heat from the burn was conducted into the lotion.

• The heat from the burn was radiated into the lotion.

In what ways are evaporation and condensation similar?

• Both cause decreases in air temperature.

• Both cause increases in air temperature.

• Both are caused by the warming of the

  atmosphere.

• Both are caused by changes in heat energy.
