Question About Temperature?

Question

I know what temperature is, but what exactly is it? I need a definition. Is it how hot or cold the air is or is it something else? I know its kind of a stupid question, but I was just thinking about what "temperature" actually measures.

Answer 1

Temperature: a measure of the warmth or coldness of an object or substance with reference to some standard value.

Answer 2

The real definition of temperature is the measure of the average speed of air molecules. Temperature is measured in degrees by using a thermometer .They are read  in the shade because their measurements are too high when placed in direct sunlight.

Even though temperature changes every day and every season, the Earth's temperature is always in the right range to support life.

The temperature of the air depends on the temperature of the surface directly below. Also, the air feels colder as you climb up a mountain. This happens because the temperature decreases as you move away from the surface. The weather is strongly affected by the temperature.

Answer 3

Temperature is the measurement of the total kinetic energy within atoms or molecules.  Heat is the transfer of that kinetic energy from one medium to another.  The higher the temperature, the faster the particles move.  At absolute zero, which is the lowest possible temperature, the kinetic energy disappear completely.  That's why solids turn into liquids, and then gasses when the temperature rises.  

Answer 4

Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter generally has the greater temperature. Specifically, temperature is a property of matter. Temperature is one of the principal parameters of thermodynamics. On the microscopic scale, temperature is defined as the average energy of microscopic motions of a single particle in the system per degree of freedom. On the macroscopic scale, temperature is the unique physical property that determines the direction of heat flow between two objects placed in thermal contact. If no heat flow occurs, the two objects have the same temperature; otherwise heat flows from the hotter object to the colder object. These two basic principles are stated in the zeroth law and second law of thermodynamics, respectively. For a solid, these microscopic motions are principally the vibrations of its atoms about their sites in the solid. For an ideal monatomic gas, the microscopic motions are the translational motions of the constituent gas particles. For a multiatomic gas, vibrational and rotational motion should be included too.
