Heat Transfer

Front

What will most likely happen to the temperature of the metal spoon when left in boiling water?

Back

The temperature of the metal spoon will

increase because heat energy from the boiling

water will transfer to the spoon.

Rose makes a cup of hot tea. She places the cup

of tea on the kitchen table and waits for it to cool

off. When she picks up the cup a few minutes

later, she notices the kitchen table is warm where

the cup used to be. Which best explains the flow

of energy between the cup and the table?

Back

Heat transferred from the cup to the table to warm the table.

The table shows the results of the experiment

Amy did where she placed three samples, with a

starting temperature of 75°F, outside in the direct

sun, and recorded the temperatures over six

minutes. What is the best conclusion Amy can draw from

her results?

Options: The dark sand absorbs heat the fastest, The water absorbs more heat than the sand samples, The light sand absorbs the most amount of heat, The water absorbs heat the fastest.

Back

The dark sand absorbs heat the fastest.

Front

What happens to cool and warm air during convection in the atmosphere?

Back

Cool air sinks and warm air rises.

Front

What kind of energy transfer is shown by the movement of the air labeled B in the diagram?

Back

convection, when warm air rises upward, spreads out, and transfers energy as heat

Front

What is one explanation for the differences in the temperatures between an inland city and a coastal city?

Back

Large bodies of water absorb and release heat very slowly and moderate the temperature.

The map shows two Georgia cities and their

temperatures on the same day of summer at the

same time. Why is Atlanta much warmer than Tybee Island in the summer?

• Ocean currents move cool, dense air along the coast, pushing warmer, less-dense air upward toward Atlanta, decreasing the temperature in Tybee Island.
• Atlanta is farther south than Tybee Island, so it is closer to the equator and therefore always has higher temperatures.
• Atlanta has a much larger population than Tybee Island, so the greater amount of collective body heat increases its temperature.
• The Sun sets in Tybee Island before it sets in Atlanta, so Tybee Island has more time to cool off in the shade than Atlanta, decreasing its temperature.

Back

Ocean currents move cool, dense air along the coast, pushing warmer, less-dense air upward toward Atlanta, decreasing the temperature in Tybee Island.

Front

How do molecules of air in direct contact with Earth's solid, warm surface absorb heat energy?

Back

conduction

Front

The Sun emits particles of energy that heat Earth's atmosphere. What is the name of this phenomenon?

Back

radiation

Front

What causes coastal regions to have a narrower temperature range than regions that are farther inland?

Back

Water warms and cools much more slowly than land or air, insulating the land on the coasts.
