A metal spoon is left in hot soup, and the handle warms after one minute. Which process mainly moves thermal energy along the spoon?
Warm air above a classroom heater rises while cooler air near the floor moves toward the heater. What heat transfer mainly creates this air motion?
A student feels warmth on her face while standing near a sunny window without touching the glass. How does most thermal energy reach her face?
A ceramic mug on a hot plate warms where its bottom touches the plate. Which transfer method mainly heats the mug's bottom?
In a pot heated from below, hot water rises from the bottom and cooler water sinks. What process is moving thermal energy through the water?
A camper warms her hands beside a fire even though her hands do not touch the flames or smoke. What mainly transfers heat to her hands?
An ice cube melts faster on an aluminum tray than on a plastic cutting board at the same room temperature. What transfer mainly warms the ice on aluminum?
A lava lamp has wax blobs that warm, rise, cool, and sink in liquid. Which heat transfer is shown by the circulating liquid and wax?
A blacktop playground becomes hot in sunlight even on a calm day. Which process brings most energy from the Sun to the blacktop?
A metal fork becomes hot where it touches a sizzling pan. Which method moves thermal energy into the fork?
The picture shows wind blowing from the land out over the ocean, called a land breeze. When does this usually happen, and why?
A chocolate bar softens under a heat lamp while sitting on a table. The lamp does not touch it. What transfer method mainly warms the chocolate?
A tile floor feels colder than a rug in the same room because heat leaves bare feet faster through the tile. What transfer method is happening?
A microwave oven warms soup while the oven walls stay fairly cool. Which transfer method carries energy from the oven into the soup?
A teacher says a metal rod is warming by conduction. Which observation best supports that claim?
Students claim convection is moving heat in a fish tank warmed from one side. What evidence would best support convection?
A heat lamp keeps chicks warm by radiation. What evidence would support radiation as the main transfer?
A student says heat moves through a copper wire by conduction. Which evidence matches conduction?
A pot of sauce is usually heated from below. If it were heated only from the top, how would convection in the sauce change?
A student claims sunlight heats a rock by radiation. Which evidence best supports this claim?
A foam cup slows conduction. Which evidence would show the foam is acting as an insulator against conduction?
Air above a candle is said to transfer heat by convection. Which evidence supports that idea?
A student says a toaster browns bread partly by radiation. Which evidence supports radiation?
A lab group tests a plastic handle on a hot metal pan. Which evidence shows the handle reduces conduction?
A campfire warms a camper's face, while a metal poker in the fire warms along its length. Which comparison is correct?
A pan sits on a burner while water inside circulates as it heats. How do the pan bottom and water transfer heat differently?
Sunlight warms a car dashboard, and hot air inside the closed car rises toward the roof. Which comparison fits the system?
A laptop's metal base warms a desk where they touch, while a fan blows warm air out the side. Which comparison is accurate?
A person feels heat from a radiator across the room, and dust above the radiator rises in warm air. How are the transfers different?
A grilled cheese sandwich browns where it touches the pan, while warm air above the pan rises. What comparison is correct?
A solar cooker warms a black pot in sunlight, then the pot heats soup where the soup touches its inside wall. Which comparison is correct?
In a greenhouse, sunlight passes through glass to warm soil, and warm air then rises from the soil. Which comparison is correct?
A hot metal slide warms a child's shorts by touch, while the child also feels sunlight on bare arms. Which comparison is correct?
A freezer coil cools nearby air, making dense cold air sink, while a warm hand touching an ice tray loses heat. Which comparison is correct?
A student wants hot cocoa to stay warm longer in a mug. Adding a foam sleeve mainly reduces which heat transfer?
A house window loses heat on a cold night. Which change would best reduce heat transfer by radiation through the window?
A student wants soup to cool faster without changing the recipe. Which action most increases convection in the soup?
A metal handle on a pot becomes too hot to hold. Which design would best reduce conduction to the hand?
A gardener wants a seed tray to warm quickly in sunlight. Which surface would increase heating by radiation the most?
A cooler keeps ice from melting during a picnic. Which feature mainly reduces convection with the outside air?
