Heat Flashcards
The quantity of heat required to raise the temperature of one pound (.4kg) of water 1d F.
British Thermal Unit (Btu)
A unit of heat equal to 100,000 BTU
Therm
The base SI unit of temperature equal to 1/273.16 of the triple point of water.
Kelvin / K
The particular temperature and pressure at which the liquid, gaseous, and solid phases of a substances can exist in equilibrium.
Triple Point
A unit of heat equal to the quantity of heat required to raise the temperature of one gram of water 1dC at a pressure of one atmosphere, equivalent to 4.186 joules.
Calorie, Gram Calorie, Small Calorie
A temperature scale in which 32dF represents the freezing point and 212dF the boiliding point of water under standard atmospheric pressure.
Fahreinheit Scale
when you know degrees Celsius, first mltiply by 9/5 and then add 32 to find degrees Fahrenheit.
A temperature scale divided into 100 degrees, in which 0dC represents the freezing point and 100dC the boiling point of water under standard atmospheric pressure.
Celsius Scale or Centigrade Scale
When you know degrees Fahrenheit first subtract 32 and then multiply by 5/9 to find degrees Celsius.
An absolute scale of temperature having a zero point of -273.16dC.
Kelvin Scale
The hypothetical lowest limit of physical temperature characterized by complete absence of heat, equal to -273.16dC or -459dF.
Absolute Zero
Temperature as measured on an absolute scale.
Absolute Temperature
The quantity of heat required to raise the temperature of a substance by one degree,
Heat Capacity
Heat capacity per unit mass of a substance: the number of Btu required to raise the temperature of one pound of a substance 1dF, or the number of calories per gram per degree centigrade.
Specific Heat
The quantity of heat absorbed or released by a substance during a change in phase at constant temperature and pressure.
Latent Heat
The quantity of heat absorbed or released by a substance during a change in temperature without a change in phase.
Sensible Heat
