Heat Transfer 1
What type of heat transfer is when hot fluids rise and cool fluids sink?
Convection
Heat moves from the _____ object to the ______ object.
hotter ; cooler
Name two forms of precipitation.
What is Rain, sleet, hail, or snow?
Warmer air is less dense than colder air. T or F
What is False?
This star is at the center of our solar system and provides most of the system’s energy.
What is the sun?
The transfer of heat energy from the sun to Earth.
Radiation
What method of heat transfer is this?
A metal spoon sitting in a hot pot.
Conduction (energy transfer via contact)
Plants contribute to the water cycle through this process where they "sweat"
What is transpiration?
When air is forced into a smaller space with no where to go, it becomes ______________.
What is compressed?
Name the term for the path that a planet follows around the sun.
What is orbit or revolution?
What type of heat transfer occurs through direct contact when objects are touching?
Conduction
An insulator stops energy from either entering or leaving an object, no matter how different the object's energy levels are.
What is an insulator?
The energy source that drives the water cycle.
What is the sun?
What type of heat transfer is feeling the warmth from a campfire.
Radiation
The 8 planets in our solar system.
What are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune?
What method of energy transfer is this?
(Description: Heat flows from the hotter cup into the cooler hands. )
Conduction
Give one specific example of convection.
Answers will vary. The convection currents in the ocean and atmosphere.
the process by which a liquid changes into a gas due to the sun's heat
What is evaporation?
This is the layer of atmosphere we live in and where weather happens.
What is the stratosphere?
This keeps our feet on the ground and also keeps the planets in their orbit.
What is gravity?
Which type of heat transfer is responsible for winds and precipitation, playing an important role in Earth's weather patterns.
Convection
Is an object that helps energy transfer from one location to another. This transfer usually is at an increased speed.
What is a conductor?
What happens to water particles as they condense?
The particles change from a gas to a liquid due to being colder. They become more dense and form droplets.
Meteorologists measure air pressure and low air pressure can be a sign that what is coming?
What is unsettled, wet, and windy weather?
These small rocky objects mostly orbit the sun between Mars and Jupiter in a region called the ______.
What is asteroid belt?
