Insulation
Heat leaks through these in your house.
windows, doors and walls
When two surfaces rub together, the parts that touch resist movement and heat is generated.
friction
A substance's ability to absorb or lose heat.
What is specific heat capacity?
A seesaw is this type of lever.
This is the process or material used in homes that slows the transfer of thermal energy, helping keep heat in during winter and out during summer.
insulation
Heat transfer that occurs through electromagnetic waves.
radiation
What does having a higher specific capacity mean?
A substance needs more energy to raise its temperature by 1°C.
This type of simple machine is used to lift a load using a rope and grooved wheel system.
pulley
This is a measure of how well an insulating material resists or slows the transfer of heat.
r value
These types of breezes affect the climate of Calgary.
mountain breezes
At equal exposure from the sun, what will heat up faster, sand or water?
Sand
This class of levers are considered to be distance multipliers.
third class levers?
How can you keep yourself warm when it is cold outside?
wearing multiple layers of clothing
wearing warm clothes made of feathers and wool (which are good insulators)
traditional inuit people wear caribou clothing which contain trapped air for better insulation
The average of all kinetic energies of all particles in an object.
temperature
Use specific heat capacity to explain how oceans help to moderate the climate of coastal cities
Oceans moderate climate because water has a high specific heat capacity, meaning it can absorb and store large amounts of heat energy. During the day, oceans absorb heat and slow down warming of nearby land. At night, they release heat slowly, which slows cooling. This reduces extreme temperature changes in coastal areas.
This type of lever has the load between the fulcrum and the effort and is always a force multiplier.
second-class lever
This is the process of heat transfer that occurs in fluids where warmer air rises and cooler air sinks, creating a current.
convection
A person uses a lever (like a wheelbarrow) to push a load. It takes a force of 10 N to move the load. If 50 J of work is done, how far did the load move?
5 meters
