what is temperature measuring?

Answer 1

it measures the degree hotness or coldness. can be measured in kelvins, centigrade (Celsius) or Farenheit.

Temperature is a measure of the average energy of the particles (atoms or molecules) of a substance. This energy occurs as the translational motion of a particle or as internal energy of a particle, such as a molecular vibration or the excitation of an electron energy level. the hotter it is the faster the molecules move.

Answer 2

The temperature is a value relative to the amount of heat in a certain medium. Doesn't have to be temperature of air. The actual temperature of something measures how much heat is within that object.

Answer 3

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.

Overview
Temperature is a measure of the average energy of the particles (atoms or molecules) of a substance. This energy occurs as the translational motion of a particle or as internal energy of a particle, such as a molecular vibration or the excitation of an electron energy level. Although very specialized laboratory equipment is required to directly detect the translational thermal motions, thermal collisions by atoms or molecules with small particles suspended in a fluid produces Brownian motion that can be seen with an ordinary microscope. The thermal motions of atoms are very fast and temperatures close to absolute zero are required to directly observe them. For instance, when scientists at the NIST achieved a record-setting cold temperature of 700 nK (billionths of a kelvin) in 1994, they used optical lattice laser equipment to adiabatically cool caesium atoms. They then turned off the entrapment lasers and directly measured atom velocities of 7 mm per second in order to calculate their temperature.

Molecules, such as O2, have more degrees of freedom than single atoms: they can have rotational and vibrational motions as well as translational motion. An increase in temperature will cause the average translational energy to increase. It will also cause the energy associated with vibrational and rotational modes to increase. Thus a diatomic gas, with extra degrees of freedom like rotation and vibration, will require a higher energy input to change the temperature by a certain amount, i.e. it will have a higher heat capacity than a monatomic gas.

The process of cooling involves removing energy from a system. When there is no more energy able to be removed, the system is said to be at absolute zero, which is the point on the thermodynamic (absolute) temperature scale where all kinetic motion in the particles comprising matter ceases and they are at complete rest in the “classic” (non-quantum mechanical) sense. By definition, absolute zero is a temperature of precisely 0 kelvins (–273.15 °C or –459.67 °F).

Answer 4

measure th heat in the air. Without it, we may not know the temperature and we will stay at home rather than go out, look out to the clouds to read forecast.

Answer 5

it's measuring temperature

Answer 6

Actually, it's measuring the the total amount of heat of a system, based on its heat capacity, and amount of particles in that system (i.e. what is it, and how much).

Answer 7

The average kinetic energy per molecule.

Answer 8

when you measure temperature, for instance-doctor; "drop your pants little jimmy, i need to take your temperature" little jimmy-"but mommy told me not to drop my pants for strangers"
