Jane washed her hair. She dried it with warm air from a blow dryer before going to school. Which statement BEST explains why the blow dryer was able to dry Sandra’s hair quickly?
The blow dryer used electricity.
the blow dryer transferred heat
the blow dryer created sound waves
the blow dryer used mechanical energy
The area in front of a fire feels warm on a cold evening. What are the processes that cause the person in front of the fire to feel warm?
conduction and convection
radiation and conduction
radiation and convection
radiation, convection and conduction
Although the heat source is at the bottom of the beaker, all of the water is the same temperature. What keeps the water at the top of the beaker the same temperature as that of the bottom?
Heat from the burner radiates through the liquid and causes even heating.
The walls of the beaker reflect heat toward the center, so the water heats evenly.
Heated water molecules and steam rise in the beaker, carrying heat by convection.
Evaporation heats the water at the top and the flame heats the water at the bottom.
Anya placed an ice cube on the sidewalk on a warm day. The ice cube soon melted to form a puddle. What process caused the ice cube to melt?
Heat transferred through the ice cube by convection.
Heat transferred from the air to the ice cube by radiation
Heat transferred from the air and the pavement by conduction.
Heat transferred through the ice cube into the pavement by conduction
A dark-colored wall becomes warm when the sun shines on it. After sunset, a person standing a meter away can feel warmth from the wall. How does heat transfer from the wall to the person?
radiation
conduction
convection
insulation
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
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.
Kayla has a wooden rod, a steel rod, and a glass rod. How could she compare the materials to find out which transfers thermal energy BEST?
Submerge each rod in ice water to find out which loses the most heat.
Place the three rods in a freezer to find out which becomes the coldest.
Place one end of each rod in very hot water to find out which becomes hot the fastest.
Place the rods on a table in a warm room and find out which feels warmest after a period of time
Heat can move through the atmosphere as air circulates. What causes the circulation of air?
Air in the atmosphere is heated by the Sun and sinks to the ground
The ground is heated by the Sun and then heats the air, causing the air to rise.
Air loses heat to the ground and then rises upward to obtain more energy.
The Sun heats the clouds which forces the cooler air to move away and sink
What happens to the air molecules when they get heated up?
rise and expand
sink and contract
contract and rise
expand and sink
What happens to the air molecules when they cool off?
rise and expand
sink and contract
contract and rise
expand and sink
