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