Particle Model
When the temperature increases, the motion of particles of a substance do this
What is speed up?
This happens when particles move farther apart.
What is expansion?
This uses waste heat to generate electricity or heat buildings among other useful tasks
What is cogeneration?
Mechanical or electrical device for measuring temperature
What is a thermometer?
The particles of this state of matter are in a matrix.
What is a solid?
This is a measure of something's ability to do work.
What is energy?
The cycle of hot air rising, cooling and then falling, only to be heated again is called______
What is convection?
An example of a thermal energy mover.
refrigerator, air conditioner, furnace
Early thermometers did not have these.
What are scales?
The particles in this state of matter are the farthest apart of the states of matter
What is gas?
When a bimetallic strip bends up, the material on the bottom is expanding more or less than the material on the top?
What is more?
Does energy flow towards or away from a concentrated source?
What is away?

Some thermometers have a sensor. The sensor produces a ___________, which affects a __________.
What is a signal? What is a responder?
A liquid changing to a solid is called freezing or ________
What is solidification?
Using wires of two different metals twisted together, this cannot be used to measure low temperatures accurately, but it is very useful for measuring high temperatures.
What is a thermocouple?
Modern windows use argon gas to create an insulated layer in a window, what did older windows use?
What is air?
Daily Double! This is produced when a fire burns without enough oxygen.
What is carbon monoxide?
This is needed to cause ice to flow or even melt at temperatures below 00 C
What is extremely high pressure?
As high energy particles leave the surface of a liquid, the remaining liquid is cooler than the original liquid. The cool liquid then cools the surface on which it is resting. This phenomenon is called____________
What is evaporative cooling?
These are the three of the most important ideas of the particle model
What is:
All substances are made of tiny particles too small to be seen.
The particles are always in motion - vibrating, rotating, and (in liquids and gases) moving from place to place.
The particles have spaces between them.
The amount of thermal energy that warms or cools one gram of a material by one degree Celsius.
What is specific heat capacity?
Fossil fuels release this gas which is extremely irritating to people's eyes, nose and throat
What is sulfur dioxide?
He invented the Celsius scale.
Who is ___________ Celsius?
During a phase change where energy is added to a substance, the particles of the substance do this.
What is become less organized?
