Topic 2
Mechanical or electrical devices used for measuring temperature.
What is a thermometer?
Solid, liquid, and gas.
What are the three states of matter?
The transfer of energy without any movement of matter.
What is Radiation?
The energy of moving air.
What is wind energy?
They are readily available form a key part of Alberta's economy
What are fossil fuels
The temperature scale used commonly in Canada and many other countries.
What is the Celsius scale?
The measure of something’s ability to do work.
What is energy?
An object or material that can transfer energy to other objects.
What is an energy source?
Energy that we harness from Earth’s interior.
What is geothermal energy?
Liquids that evaporate easily at low temperatures incertain devices.
Refrigerants
-273.15°C or 0K
What is absolute zero?
Energy cannot be created or destroyed. It can only be transformed from one type to another or passed from one object to another.
What is The Law of Conservation of Energy?
The amount of thermal energy that warms or cools an object by one degree Celsius.
What is heat capacity?
Energy resources that can be recycled or replaced by natural processes in less than 100 years.
What are renewable resources?
It is colourless, odourless, and lethal. Many people have died in houses or in stranded cars from inhaling this gas.
What is carbon monoxide?
Was given the title Lord Kelvin and had the Kelvin scale named in honour of him.
Who is William Thomson?
• 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 motion of the particles increases when the temperature increases. The motion of the particles decreases when the temperature decreases.
What are the four features of the particle model of matter?
The change of state from gas to solid or from solid to gas.
What is Sublimation?
Uses the materials in the structure to absorb, store, and release solar energy.
What is passive solar heating?
This gas is extremely irritating to the eyes, nose, and throat. People with asthma suffer greatly from this pollutant.
What is Sulfur dioxide?
(__°C × 9/5) + __ = __°F
What is the conversion from Celsius to Fahrenheit?
He believed that an invisible substance called caloric fluid caused changes in temperature.
Who is Antoine Lavoisier?
Radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays, gamma rays, and cosmic rays.
What are the forms of electromagnetic radiation in order of decreasing wavelength(longest to shortest)?
A warming of the environment that results from human activities, such as the burning of fossil fuels.
What is thermal pollution/greenhouse gas effect/global warming?
A device that transfers thermal energy from one location to another location at a different temperature, like refrigerators and air conditioners.
What is a thermal energy mover?
