Heat Cold Particles

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

• precipitation

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.

How is heat transferred when boiling a pot of water on the stove?

• conduction

• convection

• combustion

• radiation

What causes your skin to feel warm when it is in the sun on a summer day?

• Particles in the atmosphere reflect energy from the Sun downward.

• Hot particles from the Sun still carry some heat when they reach your skin.

• The solar wind carries heated air from the Sun’s atmosphere to Earth’s surface.

• The Sun radiates energy that passes through space and the atmosphere to your skin.

Which best explains how laying on the ground and dirt keeps the animal cool?

• The coolness from the ground is transferred to the animals body, lowering the animals body temperature.

• Dirt on the ground protects the animal from the heat in the air, lowering the animal's body temperature.

• The animal's body temperature does not change, but the dirt makes the animal feel cooler.

• Heat from the animals body is transferred to the ground, lowering the animal's body temperature.

• red

• blue

• white

• pink

A teacher takes a tray of ice cubes out of the freezer. Each student takes an ice cube and holds it in their hands. They make the observations listed in the chart. The student claims that changing the temperature of the water causes a physical change that turns water into ice.

Which argument BEST supports the student’s claim?

• The ice cube is melting in the student’s hand since the hands are much warmer than the ice. Heat is being added to the ice, which causes the particles to move faster.

• The ice cube is freezing in the student’s hand since the hands are much warmer than the ice. Heat is being removed from the ice, which causes the particles to move slower.

• The ice cube is melting in the student’s hand since state is changing from a solid to a liquid. Heat is being removed from the ice, which causes the particles to move faster.

• The ice cube is melting in the student’s hand since state is changing from a liquid to a solid. Heat is being added to the ice, which causes the particles to move slower.

Students observed as small drops of water collected on the outside of a glass.
Which statement BEST describes why the water vapor in the air formed liquid water on the outside of the glass?

• The humidity outside the glass turns the vapor to liquid water.

• The water vapor pulls the water from inside the glass to outside the glass.

• The temperature of the water inside the glass is colder than the air outside the glass.

• The temperature of the water inside the glass is warmer than the air outside the glass.
