Vocabulary
Any material through which energy does not pass easily
insulator
The process of heat transfer that occurs in liquid and gases as warmer material rises and displaces colder material
Convection
Energy an object has because of its physical position or its chemical composition
Potential energy
True or false Heat is the only way kinetic energy can be transferred.
false
What happens when thermal equilibrium is reached?
The objects are the same temperature.
The transfer of energy from an object with high energy to an object with lower energy in contact with it
Conduction
Any material through which energy passes easily
Conductor
When energy is transformed from one form to another in a system, what happens to some of the energy?
“Lost” to the environment
What are the three ways energy is transferred?
conduction, convection, radiation
Is the air pressure higher or lower on Mount Everest than it is here?
lower
The energy possessed by an object in motion
Kinetic energy
Energy cannot be created or destroyed
Law of conservation of energy
Energy can transfer from to or from to
.
place to place or object to object
Why is thermal energy a form of kinetic energy?
Thermal energy is the total of all Kinetic energy in a material
Put these in order from the most thermal energy to the least amount of thermal energy. Liquid, solid, gas
gas, liquid, solid
A measure of the average amount of kinetic energy of the particles in a material
Temperature
The amount of energy needed to raise the temperature of 1 gram of that substance by 1 degree celsius
specific heat
Heat is transferred from matter with a (higher, lower) temperature to matter with a (higher, lower) temperature.
higher to lower
What are the three states of matter?
solid, liquid, gas
What is a good conductor of heat?
metal
The total of all the kinetic energy of the substance’s particles
Thermal energy
The transfer of energy in the form of electromagnetic waves
Radiation
What is a fixed volume?
The volume cannot change
The smaller amount of soup has (more, less) thermal energy than the soup in the large pot.
less
Can energy disappear?
no
