Thermal Energy
Sum of kinetic and potential energy of particles that make up an object.
Thermal Energy
Movement of thermal energy from a warmer object to a cooler object is called?
Heat
The average kinetic energy of the particles that make up a material.
temperature
heat flows from
warmer to cooler temperature
Transfer of thermal energy by light/waves
Radiation
Thermal energy moves from...
Warmer to Cooler
All objects have thermal energy but not all have heat, why?
Heat requires a transfer of thermal energy from a place of greater kinetic energy to a place of lower kinetic energy.
This object measures temperature.
thermometer
Material through which thermal energy flows easily.
Conductors
Heat rising and cooling to form currents in a fluid
convection
Everything has what type of energy?
Thermal Energy
True or False. Heat and thermal energy are the same thing.
False
What 3 scales measure temperature?
Kelvin, Celsius, and Fahrenheit
what is the opposite of conductors?
insulators
Transfer of thermal energy between materials by collision of particles.
Conduction
The Three ways thermal energy is transferred are...
Radiation, Conduction, Convection
In order to have heat. An object must have?
Thermal energy and a transfer of high kinetic energy to low kinetic energy.
What are the states of matter?
solids, liquids, and gasses?
Why do we put insulation in our homes?
To keep heat in when it is cold outside and to keep heat out when it is warm outside.
True or False: Thermal energy travels to Earth from the Sun through radiation.
True
Give an example of thermal energy transferred by conduction.
Metal spoon in boiling water. Metal making contact with flame in fireplace. Pots and Pans on a burner.
True or false. Does hot cocoa heat the surrounding air? explain your reasoning.
True. Because heat moves from hot to cold and the air is colder.
Water freezes at what temperature?
Water freezes at 0 degrees Celsius and 32 degrees Fahrenheit,
This material is one of the best conductors
metals
True or False: A metal spoon gets hot in boiling water through conduction.
True
Give an example of thermal energy transferred by radiation.
The sun warming the earth.
Explain how an ice cube melts in your hand.
Thermal energy from your hand is transferred to the ice cube.
True or False: An object with a higher temperature will have slower moving particles in it. Explain your reasoning.
False. It's particles are moving faster if the temperature is higher.
Name 3 insulators, and 3 conductors
Insulators: Wool, wood, rubber, air etc. Conductors: Copper, brass, aluminum, tile etc.
Boiling pasta water is an example of...
Convection
