Thermal Energy
This is defined as the total amount of potential and kinetic energy in an object
What is thermal energy?
Heat transfers in these three different ways.
What is conduction, convection and radiation?
These three states of matter are most common on earth.
When describing how something interacts with heat, scientists describe those items as either of these two terms.
What is a conductor or an insulator?
When you feel something cold, you are really feeling this.
As thermal energy increases in an object the particles of it will begin to do this
What is move faster, vibrate more?
When heat is transferring, it always moves in this direction.
What is warm to cool?
When you increase the thermal energy of a solid, it may become a liquid by undergoing this process.
What is melting?
You leave a metal spoon in a cup of hot chocolate. You notice that the handle is now warm. We would say the spoon is a what?
What is a conductor?
Warm air/water is up top and cool air/water is on the bottom.
As thermal energy in an object decreases, the object will likely do what? Hope the air on my tires doesn't get too low.
What is contract?
This type of heat transfer occurs when you cook bacon on the stove.
What is conduction?
On warm summer day, you can see water turn into steam through this process.
What is evaporation or boiling?
Its thanksgiving day and you are pulling a pie out of the oven. The oven mits you are wearing act as this to prevent the heat from transferring to your hands.
What is an insulator?
Popcorn is a great example of this property that occurs when an object is heated up. Hope there is butter and salt too!
What is thermal expansion?
This is a measurement of the average kinetic energy in the particles of an object. In science, we measure it in celsius.
What is temperature?
Cool air comes in from the gulf of mexico, it heats up as it goes over land, and then circulates back to the gulf. This is made possible by this type of heat transfer.
What is convection?
In northern states, drivers are afraid that rain in the night time may become black ice after it undergoes this proccess.
What is freezing?
As you walk on a tile floor in bare feet, you can feel how cool the tile is. This feeling tells you that the tile is clearly a good one of these.
What is a conductor?
Thermal energy and heat are often mixed up. A good scientists would say that the difference between the two is...
Thermal energy is the measurement of all energy in an object, where as heat is the transfer of thermal energy.
This is the name given to an item that has no particle movement at all. Must be really cold...
What is absolute zero?
Two part answer here. As you sit next to a fire place, you feel the heat as it warms your toes through this type of heat transfer. At the same time, a blanket wrapped around your shoulders acts as one of these.
What is radiation and an insulator?
This process occurs as you lower the thermal energy of an item, like when the water vapor in your breath becomes liquid water on a window.
What is condensation?
Metal flagpoles are really good conductors. This means that if you were to touch one, you would feel this.
What is heat transferring from the pole to your hand?
No matter what, heat is a type of energy so it follows the Law of conservation of energy which states this.
