measure the average kinetic energy of the particles of an object or substance. It is like a speedometer for how fast particles are moving!!
Temperature
Heat flows from hotter block to cooler block.
Until what is achieved???
What is thermal equilibrium
Materials the don't allow heat energy to pass through them well are called ???
What is insulators.
What is conduction.
transfer of heat through empty space by invisible electromagnetic rays. No matter is required for the heat transfer to occur.
What is radiation?
The flow of energy from warmer places to cooler places due to difference in temperature.
What is heat
The heat that you feel radiating from a fire to warm your hands to thermal radiation.
The sun's rays travel through the empty space between the sun and our planet.
What is radiation.
When you boil water in a pot, the water near the burner gets hot and becomes less dense. It rises up and pushes the cooler water out of the way. The cooler water sinks, gets heated, becomes less dense, and rises up. This creates a __?___ currents.
What is "Convection currents"
Moving fluids result in a transfer of heat in a cycle called __??___ current.
What is "Convection Current".
transfer of heat in a fluid (a gas or a liquid) caused when hotter, less dense fluids rise and cooler, more dense fluids sink. Moving fluids result in a transfer of heat in a cycle.
What is Convection
When a basboard heater is used in a room, heat is distributed throughout the air in the room due to _?__currents.
What is "Convection"
The energy of an object because of motion. This word stems from the Greek work for motion.
What is "Kinetic Energy"
True or False...
The size of an object or the amount of a substance does not affect the temperature.
What is "true".
What are the three temperature scales?
What is "Celsius, Kelvin, and Fahrenheit"
materials that allow heat energy to move through them efficiently. Particles are typically close together (dense), like in metals.
True or False
An object or system does not have heat. Heat is the transfer or flow of thermal energy due to temperature differences.
What temperature does water freeze in Celsius?
What is "0 degrees Celsius"
True or False...
Heat moves from cooler to warmer objects.
What is "False"
What is "100 degree Celsius"
happens when heat flows from a higher temperature object to a lower temperature object until the two objects have an actual temperature.
What is thermal equilibrium
If there are two pots of water boiling. One is big and one is small. The two pots have the same temperature but the bigger pot has more energy. If this is true, explain why...
What is "True, the bigger pot has more energy because there are more molecules in motion in the big pot than in the little pot or in the match."
True or False....
Heat will continue to flow out of the kettle (tea pot) until the kettle and the air around it reaches differing temperatures.
What is "False, thermal equilibrium"
