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