the energy of motion
the transfer of thermal energy from a warmer to cooler object
The AVERAGE kinetic energy that the particles in a substance has
The TOTAL kinetic energy that the particles in a substance has
faster moving particles will have _______ kinetic energy and therefore a _______ temperature than slower moving particles
The transfer of heat by direct contact between particles
The transfer of heat through empty space by electromagnetic waves
The transfer of heat by warmer fluids rising and cooler fluids sinking
Explain how conduction works
Explain how convection works
Heat always moves from _________ to __________
T or F: The temperature of a substance depends on how much of the substance you have
T or F: The thermal energy of a substance depends on how much of the substance you have
In which phases of matter do the particles have kinetic energy?
What are the 3 scales for measuring temperature?
materials that transfer thermal energy well
materials that do NOT transfer thermal energy well
Give two examples of conductors
Give three examples of insulators
What are insulators used for?
you burn your hand when you touch the metal end of a curling iron
a heater located in the deep ened warms an entire swimming pool
the sunlight shines directly on you through the window making you feel hot
Your feet feel cold as you walk onto the tile floor in your bathroom
when you sit facing a campfire, your face feels warm but your back feels cold
What is kinetic energy?
What is heat?
What is temperature?
What is thermal energy?
more; higher
What is conduction?
What is radiation?
What is convection?
when substances come in contact with each other, the particles bump into each other giving away some thermal energy
fluids close to the heat source warm up, the particles spread out, becoming less dense, fluid rises; cooler fluid is less dense so it sinks
warmer to cooler
False
True
All phases
Fahrenheit, Celsius, and Kelvin
What are conductors?
What are insulators?
glass, metal, tile
various answers
use to prevent or slow down the transfer of thermal energy
conduction
convection
radiation
