Topics 1 and 2
A device used to measure temperature.
What is a thermometer?
The ability to do work and to cause change.
What is energy?
Amount of thermal energy that warms or cool one gram of a material by 1°C.
What is specific heat capacity?
Transfer of energy without any movement of matter.
What is radiation?
Liquids that evaporate easily at low temperatures.
What is a refrigerant?
Temperature scale used commonly in Canada and in many other countries.
What is the Celsius scale?
Solid, liquid, and gas.
What are the three states of matter?
Water escaping from a cup.
What is vaporization?
Energy source, direction of energy transfer, transformation, waste energy, and control systems.
What is the Energy Transfer System?
Key part of Alberta's economy.
What are fossil fuels?
-273°C.
What is absolute zero?
•Substances made of tiny particles too small to be seen.
•Particles are always in motion- vibrating, rotating, moving from place to place.
•Particles have spaces between them.
•Motion of particles increases when the temperature increases, the motion decreases when the temperature decreases.
What is the Particle Model of Matter?
Materials keep their shape and size.
What is a solid?
Can travel through:
• Empty space
• Air
• Glass
What is electromagnetic radiation?
Produced when fire burns without enough oxygen.
What is carbon monoxide?
Used to measure very high temperatures that normal thermometers fail at.
What is a thermocouple?
Energy cannot be created or destroyed. It can only be transformed from one type to another.
What is The Law of Conservation of Energy?
The temperatures stays the same.
What is a phase change?
Uses materials in a structure to absorb, store, and release solar energy.
What is passive solar energy?
Can lead to acid rain.
What is sulfur dioxide?
Can be photographed with special films or detected by electronic sensors that display images on television screens.
What is infrared radiation?
An invisible substance that caused changes in temperature, later proved to be false.
What is caloric fluid?
Individual particles that make up the material start to break apart into tinier pieces called ions and electrons. Extremely high temperatures are required.
What is plasma?
Uses waste heat to generate electricity, heat building, or do other useful tasks.
What is cogeneration?
Tells the consumer how much electricity an appliance uses in one year under normal use.
What is The EnerGuide label?
