Section 1
Want or need: Miss Y buying a dishwasher for her house.
What is a want?
This explains all matter is made of tiny particles that are always moving, have space between them, and move faster when they heat up.
What is the Particle Model of Matter?
This device utilizes a bimetallic strip to flip a switch and control the temperature of a room.
What is a thermostat?
These non-renewable energy sources formed from the remains of plants and animals millions of years ago.
What are fossil fuels?
The two types of heating systems.
What are central and local?
Want or need: Miss Y wearing warm clothing to walk to school in Alberta winter.
What is a need?
The distinct characteristic that sets water apart form other liquids on Earth.
To prevent heat loss, you want a higher R-value of this.
What is insulation?
Higher concentrations of these in the atmosphere lead to global warming.
What are greenhouse gases?
The state change from gas to solid.
What is deposition?
What is caloric?
A state of matter in which particles are not connected and have the most kinetic energy.
What is gas?
The primary source of energy that warms the Earth.
What is solar energy?
Using our energy resources in a way that meets our current needs without compromising the needs of future generations.
What is sustainability?
100 oC
What is the boiling point of water?
The only type of heat transfer that does not require matter.
What is radiation?
A specialized photograph to see heat loss in a building.
What is a thermogram?
This energy-saving process involves using waste heat from power plants in nearby buildings.
What is cogeneration?
What are the walls?
The coldest possible temperature (in oC!)
Temperature is a measure of this specific property within the particles of a substance.
What is the average kinetic energy of the particles?
This substance evaporates to absorb thermal energy from the surrounding air.
What is a refrigerant?
The largest user of energy in the country.
What is industry?
