Temperature Flashcards
Temperature
The temperature of a substance is a number which expresses its degree of hotness on some chosen level/ (NOT HEAT ENERGY)
Heat
A form of energy measured in joules
Thermal equilibrium
When the number of heat temperatures are the same for two bodies in contact there is no heat flow between the body’s
Heat transfer
When two bodies are put in contact heat flows from the body of high temp to low
Thermometric property
A physical property of a substance whose value varies continuously from its the degree of hotness of the body
Rules for defining a temperature scale
Select a thermometric property
Select two fixed points
Divide the interval between the fixed points (called the fundamental interval) into equal sub intervals
Calibrating a mercury thermometer to read temperature in the Celsius scale
