100
This device, invented by Galileo in the 1600s, used air to raise or lower a bubble of liquid depending on temperature.
What is an air thermometer
100
Too small to be seen, have spaces between them and are always in motion are 3 important points of this.
What is the particle theory(model) of matter?
100
Engineers put these in bridges to allow the different parts to expand and contract.
What are expansion joints?
100
This is the same temperature as the freezing point of a substance.
What is the melting point?
100
The missing component in a hydro-electric dam that comes between the turbine and the electricity that is produced.
What is a generator?
200
This will cause a liquid to boil at a lower temperature the higher you go up.
What is air pressure?
200
This state of matter always has the particles moving the fastest and are furthest apart.
What is a gas?
200
This is the amount of thermal energy that warms or cools 1 gram of a material by 1 degree Celsius.
What is specific heat capacity?
200
This combination of colour and texture would absorb energy well.
What is dark and dull?
200
The type of solar heating that requires complex equipment to distribute heat throughout a building.
What is active solar heating?
300
This Celsius temperature rarely changes in humans because the body gets rid of excess heat by perspiration and evaporation.
What is 37 degrees?
300
This indicates the average speed of the particles or kinetic energy of a substance.
What is temperature?
300
Most common substances are these two states of matter at room temperature.
What is a gas and solid?
300
Convection does NOT occur in this state of matter.
What is a solid?
300
This form of conservation happens when waste heat is re-used to create energy.
What is co-generation?
400
When heated, this device will bend because one of the metals expands more than the other.
What is a bimetallic strip?
400
These will slow down when thermal energy (heat) is decreased.
What are particles?
400
This "trick" using water is sometimes used by homeowners to cool a surface outside their house.
What is evaporative cooling
400
This material would be useful if you wanted to transfer heat easily from one object to another.
What is a heat conductor?
400
Refrigerators and air conditioners are examples of this.
What is a heat mover?
500
This scale is used mostly by scientists to describe very cold temperatures.
What is the Kelvin scale?
500
This substance when cooled will actually increase in size as it changes from a liquid to a solid.
What is water?
500
This happens when warm, moist air touches a cold surface.
What is condensation?
500
The higher this value is for a material, the better it is as an insulator.
What is RSI value?
500
This device reduces energy consumption by always having hot water immediately available at the tap.
What is a recirculating hot water pump?
