Temperature is an indirect measure of the kinetic energy of particles composing matter. The SI unit for temperature is the kelvin (K). There is no degree sign associated with the kelvin. Kinetic-molecular theory asserts that temperature is a property...

There are several equivalent definitions of temperature. In thermodynamics, temperature is defined as a property of an object that determines the direction of heat flow. Heat always flows from a higher temperature region to a lower temperature region....

Temperature is usually defined as the degree of an object's heat energy. The higher the energy level, the hotter the object. When two objects are placed next to each other, heat energy will always travel from the hotter to the colder object....

Temperature is a thermodynamic term (i.e., referring to the supply, use, or conversion of energy) referring to the average thermal energy in a system. (Thermal energy, or heat, is a type of kinetic energy, which is due to the rate of vibration of ato...

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. Temperature is one of the principal parameters of thermodynamics. On the microscopic scale,...

To freeze or not to freeze-that is not a question When you live in an "extreme" part of the country (hot, cold, big or little), you can predict what will be said right after someone finds out where you're from. It will be...

More than 50,000 scientists from 63 nations turned their attention to the world's poles Monday to measure the effects of climate change, using icebreakers, satellites and submarines to study everything from the effect of solar radiation on the polar atmosphere to the exotic marine life...

Nevada is among the states with the most dramatic increase in average temperatures the last 30 years, according to a new study that examines the impact of global warming across the country.The average temperature in Reno from June through August last year was 75.6 degrees,...
