Particle Movement
When a material's temperature is rising, this is happening to its particles.
What is moving faster?
This kind of thermal energy transfer is why cookies can be baked in the car on a really toasty summer day in Arizona.
What is radiation?
K.E. + P.E. =
What is Thermal Energy?
A thermostat uses these kind of coils to signal when to turn on or off the heating system.
What are bimetallic coils?
This type of material makes excellent thermal conductors.
What is metal?
When potential energy is being removed from a material, its particles are doing this.
What is moving closer together?
This movement of thermal energy includes the transfer of some thermal energy between particles of different materials as they collide.
What is conduction?
The movement of fluids in a cycle because of convection.
What is a convection current?
Heating moves in this direction.
What is from a warm area to a cooler area?
This is the formulaic equation for density.
What is D = m/V?
If ice and water have the same temperature, why does one stay solid, while the other is a liquid?
-OR-
Their particles are at differing distances apart from each other.
Arizona is a desert due to this kind of movement of thermal energy.
What is convection?
A machine that converts thermal energy into mechanical energy.
What is a heat engine?
A refrigerator uses this to abide by the natural movement of heat.
What is coolant?
As particles expand in air, eventually the warm air...
What is rises?
This is happening to particles during thermal contraction.
Radiation travels through these.
The average kinetic energy of particles in a material.
What is temperature?
Name an animal that might live near the equator.
(Any rainforest animal - since rainforests are found near the equator).
The point at which particles are moving fast enough and far enough to change their state of matter is called this.
What is melting point? (Or boiling, condensing, freezing)
The amount of thermal energy required to increase the temperature of 1 kg of a material by 1 degree Celsius is this.
What is the specific heat?
This is the movement of thermal energy from a warmer location to a cooler location?
What is heat?
A device that converts electric energy into thermal energy is called this.
What is a heating appliance?
As particles warm up, they begin moving further apart as they move faster. This causes their volume to increase, but this to decrease as a result.
What is density?
