Matter & Compounds
This is commonly defined as a substance that occupies space and has mass.
Matter
If this value is greater than 1, a substance will sink in water; if it is less than 1, the substance will rise.
Specific Gravity
This law states that the volume of a gas varies inversely with absolute pressure, provided the temperature remains constant.
Boyle's Law
Water boils at 212°F at standard sea-level conditions, which equals this temperature on the Celsius scale.
100°C
Often called 'hidden heat,' this type of heat results in a phase change without a change in temperature.
Latent Heat
This type of substance is formed when atoms from one substance combine chemically with atoms from another.
A Compound
This property is defined as the volume that each pound of a gas occupies.
Specific Volume
This law states that the total pressure of a confined mixture of non-reacting gases is the sum of the pressures of each gas.
Dalton's Law
Standard atmospheric pressure at sea level is measured as this many inches of Mercury (in. Hg).
29.92
This fundamental law states that energy is neither created nor destroyed, only converted from one form to another.
Law of Conservation of Energy
It is used in the English measurement system by the United States.
Fahrenheit scale
Unlike solids which only exert force downward, this state of matter exerts force in all directions.
Vapor
Standard atmospheric pressure at sea level is exactly this many psia.
14.696
This is the name given to the absolute temperature scale based on Fahrenheit.
The Rankine Scale
This rate is determined by the difference in the level of heat (temperature) between two substances.
Heat Transfer Rate
The term used to indicate the space a weight of gas will occupy.
Specific volume
If the density of tungsten is $1210 lb/ft3, this is its specific volume in ft3/lb.
0.000826
It's where a Bourdon tube is often found
Pressure Gauge
Where all molecular biology activity stops.
-460°F
"The amount of heat required to raise the temperature of 1 pound of water by 1° F" is known as
A British Thermal Unit (1 BTU)
Good ventilation is important when working around refrigeration equipment because modern refrigerants ____.
Are heavier than air and may displace the oxygen around you
A ton of refrigeration.
288,000 Btu/24 h
It's when the vacuum begins
500 microns (300-500)
As temperature of a material increases, the molecules in the material...
Travel faster
This relationship correlates the vapor pressure and the boiling point of water and is the basis for controlling the cooling system’s temperatures.
