Direct contact or conduction

An alligator is cold blooded. When it is cold, the alligator looks for a warm place to lay, like on the sand or a rock warmed by the sun. How does the sand or the rock warm the alligator?

Radiation

Bruce left some butter out in his kitchen. Bright sunlight came in through the window and melted the butter. Heat energy from the sun is called

Radiation

Burning logs in the fire place produce heat energy. We get warm from the fire when heat energy is transferred by

Farther apart and more faster

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

heat travels from the hotter object to the cooler object.

Energy is transferred in solids by conduction, which means that

Radiation

Heat from the sun moves through space by the process of

A stove and a copper pot

Heat would best be transferred by conduction between

Radiation

Microwave ovens heat food through the process of

Conduction

Marina is cooking soup in a pot on the stove. The pot is in direct contact with the stove. In this case, heat energy is transferred to the soup by

Heat energy from the soup is transferred to the spoon

Marina is using a metal spoon to stir her soup. Why does the spoon feel warm?

Convection

Molecules of two solid substances actually collide with each other to transfer energy in this method of heat transfer

Convection

The heat transfer depicted in the image is MOST likely

Radiation

The method of heat transfer by which the sun warms the earth is

Conduction

The name for heat transfer between two solid which are in direct contact or touching one another is

Convection

The process by which hot and cold air are transferred in the atmosphere is

Radiation

The sun heats Earth mainly through

In space

This process of heat transfer by conduction would NOT work

Convection

This process of heat transfer is BEST described as

Conduction

What is the main method of heat transfer from the core to the crust of Earth?

Conduction

When ironing cloths the primary method of heat transfer is

Convection cells

When mantle rocks near the radioactive core are heated, they become less dense than the cooler, upper mantle rocks. These warmer rocks rise, while the cooler rocks sink. This movement of warmer and cooler mantle rocks creates pockets of circulation within the mantle called _________, which are thought to be the force behind the movement of tectonic plates over the asthenosphere.

Aluminum

Which material would be best to use for heating up food

with the windows rolled up gets very hot on a summer day.

Which observation would be evidence that heat was transferred by radiation?

Metal is a conductor

Why does a metal spoon left on a bowl of hot soup become warm

skillet is gaining energy (heat) from the stove.

cold cast iron skillet is placed onto a stove top. When the stove is turned on, the skillet becomes very hot. Why does the skillet become hot?

molecular movement in the first rod transferred energy to the molecules in the second.

iron rods are placed horizontally, touching end-to-end. One end of one rod is heated. After some time, the other rod also feels warm to touch. How did the heat travel from the heated rod to the one that was not heated?

Radiation

light from the sun warms the ground, the transfer of heat energy is called

Circulated the hot air

new type of oven that cooks food quickly and more completely is the convection oven. The key difference in this type of oven and a regular oven is that it

Through space

process of heat radiation is the ONLY method of heat transfer that can occur

You will see the green colored water move and mix with the cold water due to convection.

tank of water is separated into two sections. Hot green water is placed on one side of the tank and clear cold water is placed on the other side. What would you predict will happen when the partition separating the tank is removed? Why?
