Energy Transfers
This type of energy transfer allows sunlight to warm the Earth, even across the vacuum of space.
What is radiation?
Your ice cream has become soup.
What is melting?
You grab a metal railing and it feels very cold.
What is hand to railing?
This measures the average kinetic energy of the particles in a substance.
What is temperature?
Pour hot water into a mug and the mug gets warm by this process.
What is conduction?
Water, at 100 degrees celsius.
What is boiling?
Ouch! that pan is Hot!
What is pan to hand?
As the temperature of a material increases, the average kinetic energy of its particles does this.
What is increases?
Warm water rising through cooler water causes this type of energy transfer.
What is convection?
A pot of water is left on the stove. Later the water is gone.
What is vaporization? (due to boiling)
Building a snowman, with no gloves!
What is hand to snow?
During a phase change the temperature does this.
What is stays the same?
Your hand feels cold when you grab a soda from the fridge because heat moves directly from your hand into the bottle by this method.
What is conduction?
After a hot shower, the mirror becomes foggy.
What is condensation?
Get the frozen pizza out, it's time for dinner!
What is hand to frozen pizza?
As the temperature of a material decreases, the average kinetic energy of its particles does this.
What is decrease?
Hot air rising from a fire mixes with cooler air above.
What is convection?
Wet clothes on a clothes line are now dry!
What is vaporization? (due to evaporation)
I love holding my hands up to a nice hot fire.
What is fire to hands?
When the heat stops flowing between objects, they have reached this state.
What is thermal equilibrium?
