Which describes what can happen as a result of radiation?

• A piece of wood burns in a fire.
• A shirt is hot after having been ironed.
• A can of soup in heated in a pot on a stove.
• A car's inside temperature rises to over 100 degrees on a sunny day.

Which is most responsible for the uneven heating of the air in the atmosphere?

• radiation
• convection
• conduction
• condensation

Which is the best example of heat transfer through radiation?

• heating soup in a pot on the stove
• standing b a campfire to get warm on a chilly night
• burning your hand when touching a hot pan on the stove
• not getting burned when touching a wooden spoon that has been in a hot pan

A student places a cup of cold water on a counter in a hot room. After a short time, the students 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 tot he 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 does heat energy from the sun reach Earth?

• conduction
• convection
• insulation
• radiation

Jill notices that her skin gets burned when she sits out in the sun. What best explains why this happens?

• The soil is convecting heat into the air.
• The heat from the sun is being conducted to Earth.
• The heat from the sun is radiating down to Earth's surface.

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 statement best describes how winter weather can damage roads?

• Snow and ice can cause car accidents, which damage roads.
• Rain, ice, and snow can cause the painted lines on roads to fade.
• Cold temperatures can cause road materials to expand, creating potholes.
• Water can get into cracks in roads, then freeze and expand, making the cracks worse.

Which best explains why most pot handles are made of plastic?

• Plastic conducts heat and stays cool.
• Plastic does not conduct heat and stays cool.
• Plastic does not radiate heat and warms up.

Which best explain why a full glass bottle of water should not be stored in a freezer?

• The temperature of the freezer will make the water too cold.
• Water expands when it freezes, which could break the bottle.
• Water contracts when it freezes, which could break the bottle.
• The temperature of the freezer will not make the water cold enough.
