absolute zero: lowest possible temperature
9.
air: poor conductor
10.
bimetallic strip: device of two different metals stuck together that will bend because of differences in expansion rates
11.
calories: units by which heat is measured or the amount of heat need to raise the temperature of 1 gram of water by 1ยบ celsius
12.
conduction: how heat is transferred through direct contact of molecules
13.
convection: how heat is transferred in currents of liquids or gases
14.
coolant: liquid that undergoes a phase change to gas and then back to liquid in refrigerators
15.
fahrenheit, celsius, and kelvin: three units of temperature measurement used by thermometers
16.
fire triangle: diagram showing the three things (heat, oxygen, and fuel) needed for something to burn (combustion)
17.
glass wool: okay conductor
18.
heat: kind of energy also called thermal energy
19.
insulator: substance that is good at reducing the transfer of heat
20.
kindling point: point at which paper will burn
21.
kinetic energy: energy of motion
22.
law of conservation of energy and matter: states that "energy can neither be created nor destroyed but can be changed from one form to another."
23.
law of entropy: explains how heat always moves from a warmer to a cooler region and how energy is lost and becomes more disordered

matter: anything that has mass and occupies space
25.
metal: best conductor

36.
thermometer: instrument used for measuring temperature
37.
thermostats (some thermometers): the instrument that uses bimetallic strips as a switch or gauge
38.
why ice floats in water: water expands as a solid and is less dense than liquid water
39.
work: force causing an object to move
