Temperature: Temperature is the physical property of a system which underlies the common notions of "hot" and "cold"; the material with the higher temperature is said to be hotter. Temperature is a measure of the average kinetic energy of the particles in a sample of matter. In other words, temperature is a meas...

Weather: Weather comprises all the various phenomena that occur in the atmosphere of a planet. "Weather" is normally taken to mean the activity of these phenomena over a period of a few days. The average weather over a longer period is known as the climate. This aspect of the weather is studied with great in...
