Heat Transfer

As a student in an environmental science class, you have been asked to explain the greenhouse effect and the problem we face, in regards to global warming with increasing greenhouse gas emissions. You decide to use an analogy to help your other classmates understand how the increase in greenhouse gases will play a role in the greenhouse effect and global warming. All BUT ONE of these analogies is correct.

• The increase in greenhouse gas emissions is like wearing a sweatshirt while you are running.

• The increase in greenhouse gas emissions is like putting on extra layers of clothes during the winter.

• The increase in greenhouse gas emissions is like placing an extra log on the fire to produce more heat.

• The increase in greenhouse gas emissions is like pulling an extra blanket over you while lying on the couch.

Nick's class did an experiment. They put the same amount of water into four paper cups. To start, the temperature was the same in each cup. They put the cups in four different places. They left them for thirty minutes. Next, they used a thermometer to find the temperature of each cup of water. Predict which location should have the highest temperature.

• the cup on the desk in the classroom

• the cup in a sunny spot on the grass

• the cup outside, in the shade of a tree

• the cup in the dark corner of the classroom

Most of the energy needed for all the processes on earth comes directly or indirectly from the sun. There is no medium or material connecting the sun to the earth. Therefore, the only type of heat transfer possible to transfer energy from the sun to the earth is

• condensation

• conduction

• convection

• radiation

At the beach, differences in temperatures create wind which transfers heat between the land and the water. The same process is also seen in the ocean as the gulf stream carries heat from the tropics northward. Heat transfer through any intermediate fluid is known as

• condensation

• conduction

• convection

• radiation

Conduction occurs more easily between solids and liquids. This is because the particles in gases are

• farther apart and move faster.

• closer together and move faster.

• further apart and move more slowly.

• closer together and move more slowly.

Heat would best be transferred by conduction between

• a candle and the air.

• an oven and a glass dish.

• a stove and a copper pot.

• water and a wooden spoon.
