Why do hot fluids rise and cool fluids sink?
Hot fluids rise because they become less dense and cool fluids sink because they become denser.
100
Heat moves from the _____ object to the ______ object.
hotter ; cooler
100
Feeling warmth from a campfire.
Radiation
200
The transfer of heat energy from the sun to Earth.
Radiation
200
The current of hot magma rising and cool magma sinking.
Convection
200
Accidently burning your hand on a hot metal pan.
Conduction.
300
Do the molecules in a cube of ice move or are they completely still?
They still move a little. Cool things still have heat energy that moves the molecules.
300
What method of heat transfer is this?
Conduction (energy transfer via contact)
300
La radiación es cuando las ______ viajan a través del espacio, sin contacto directo.
ondas
400
What method of energy transfer is this?
(Description: Heat flows from the hotter cup into the cooler hands. )
Conduction (energy transfer via contact)
400
What method of heat transfer is shown in the photo?
It is showing heat radiation and how the mesh over the rabbit is an insulator blocking the transfer of heat from the rabbit.
400
What is one way you can protect yourself from the sun's radiation?
Wear sunblock. Wear protective clothing. Don't go out as much when the sun is its brightest.
500
What method of heat transfer is shown here?
Convection heating (hot fluid rises, cool fluid sinks)
500
Describe an example of radiation.
Answers will vary. The warmth we feel from a fire.
500
Explain why it’s much colder at the bottom of a pool than at the top. Also, describe what heat transfer processes are taking place.
Convection makes the cool water sink and hot water rise. Radiation heats the surface of the water and may not penetrate down to the bottom.
600
What are two different words we use to describe temperature?
Kelvin, Celsius or Fahrenheit
600
Draw an example of convection.
Answers will vary. The convection currents in the ocean and atmosphere.
600
draw an example of conduction.
Answers will vary and must involve direct contact.
