What is temperature and what does it measure?

Answer 1

Temperature is a measure of thermodynamic activity. Molecules of substances vibrate due to thermodynamic energy. When the substance gains heat, this energy increases and the vibrations become more vigorous. This is reflected by an increase in temperature.

Answer 2

Temperature is a comparative objective measure of hot and cold. There are various ways to make such a comparison, e.g. detection of heat radiation, particle velocity, kinetic energy, bulk behavior of a thermometric material (most common). All temperature scales (e.g. Celsius, Fahrenheit, Kelvin) must be defined by an initial standard; for example, the Celsius scale is defined as 0 degrees Celsius being the freezing point of water and 100 degrees Celsius being the boiling point of water.

Answer 3

The absolute measure of temperature is Kelvin.

The most common measure is degrees Celsius (or centigrade) but there are also degrees of the Fahrenheit, Reaumur, Rankine, Romer, Delisle and Newton scales.

Answer 4

You measure the amount of thermodynamic activity in a body.
