what is temperature?

Answer 1

Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter has the greater temperature. Temperature is one of the principal parameters of thermodynamics. The temperature of a system is related to the average energy of microscopic motions in the system. For a solid, these microscopic motions are principally the vibrations of the constituent atoms about their sites in the solid. For an ideal monatomic gas, the microscopic motions are the translational motions of the constiutent gas particles

Temperature is measured with thermometers that may be calibrated to a variety of temperature scales. Throughout the world (except for the U.S.), the Celsius scale is used for most temperature measuring purposes. The entire scientific world (the U.S. included) measures temperature in Celsius, and thermodynamic temperature in kelvins. Many engineering fields in the U.S., especially high-tech ones, also use the Kelvin and Celsius scales. The bulk of the U.S. however, (its lay people, industry, meteorology, and government) relies upon the Fahrenheit scale. Other engineering fields in the U.S. also rely upon the Rankine scale when working in thermodynamic-related disciplines such as combustion.

Answer 3

Temperature is the measure of degree of hotness or coldness of the body.Any matter has some internal energy present in it at any given temperature.This energy is in various forms like translational.vibrational,thermal, kinetic,rotational etc. All these forms of energy seize to exist once the temperature reaches absolute zero(0 K).Hence the temperature is nothing but estimation of the energy content of the matter.A gas at higher temperature has higher frequency of collisions between its atoms.These collisions on wall cause the transfer of kinetic energy present to thermal energy and the temperature is estimated.In solids the higher temperature body causes the molecules of lower temperature to excite and this is reflected in the volume expansion of a lower temperature body.This is the basic principle behind measurement of temperature by mercury thermometer.

Answer 4

Temperature is a measure of the average heat or thermal energy of the particles in a substance. Since it is an average measurement, it does not depend on the number of particles in an object. In that sense it does not depend on the size of it. For example, the temperature of a small cup of boiling water is the same as the temperature of a large pot of boiling water. Even if the large pot is much bigger than the cup and has millions and millions more water molecules.

Answer 5

temperature is not the hotness or coldness of a body, it only tells about the hotness or coldness of a body. temperature is the average kinetic energy of the particles that make up a body or substance. it differs from heat, which is the total internal energy (kinetic and potential) of a system. remember kinetic energy begets heat through friction from molecular or particulate collision, that's how come it tells about hotness or its absence (coldness).

Answer 6

The measure of hot or cold.

Answer 7

the hotness or coldness of a body
