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?
