Vocab
A group of atoms joined together in a particular way
What is a molecule?
The transfer of energy through direct contact
What is conduction?
To move from one object to another or one place to another
What is transfer?
Temperature is a measure of the average of this type of energy
What is kinetic energy?
Thermal energy always moves in this direction
What is hot to cold?
A number that summarizes a set of data that can be computed by adding all the numbers in a list and then dividing by the number of numbers in the list
What is average?
Materials that are good/efficient at transferring energy, such as metal
What are conductors?
When something becomes different over time
What is change?
When a thing gets hotter, it's molecules are moving faster and have
What is more kinetic energy?
The AVERAGE amount of kinetic energy per molecule in a system/object
What is temperature?
The energy that an object has because it is moving
What is kinetic Energy?
The transfer of energy through a fluid (a liquid or a gas)
What is convection?
When something stays mostly the same over time
What is stability?
When a thing gets colder, it's molecules are moving slower and have
What is less kinetic energy?
This term describes when two objects in contact reach the same temperature
What is thermal equilibrium?
A set of interacting parts forming a complex whole?
What is a system?
Materials that are poor/inefficient at transferring energy, such as air and wood
What are insulators?
A balanced state in which a system is stable, such as when two or more samples are the same temeprature
What is equilibrium?
When a thing gains or loses energy the energy gained of loss is
What is divided (among all the molecules)?
The Eiffel Tower will expand a few inches in the summer months due to this phenomenon
What is Thermal Expansion?
The moment when two objects hit each other
What is a collision?
The transfer of energy through space (in the form of waves/particles)
What is radiation?
What is thermal energy?
The average kinetic energy (temperature) of the molecules in the system is the total kinetic energy (thermal energy) evenly divided by the number of molecules in the system
What is equilibrium?
Energy-saving light bulb that generates light through a semiconductor
What is an LED?
