Thermal radiation - Wikipedia
网页Thermal radiation is electromagnetic radiation emitted by the thermal motion of particles in matter. Thermal radiation transmits as an electromagnetic wave through both matter and vacuum. When matter absorbs thermal radiation its temperature will tend to rise. All matter with a temperature greater than absolute zero emits thermal radiation.
Thermal radiation | Definition, Properties, Examples, & Facts
网页thermal radiation, process by which energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it.
What are thermal emissions and how are they driving the climate crisis?
网页2021年2月9日 · Thermal emissions include the greenhouse gases released from the processes of heating and cooling. Here are four things you need to know about them and what WWF is doing to tackle this challenge.

What is the greenhouse effect? - NASA Science
网页The greenhouse effect is the process through which heat is trapped near Earth’s surface by substances known as ‘greenhouse gases.’ Imagine these gases as a cozy blanket enveloping our planet, helping to maintain a warmer …
How Exactly Does Carbon Dioxide Cause Global Warming?
网页2021年2月25日 · Greenhouse gases like carbon dioxide and methane absorb the infrared energy, re-emitting some of it back toward Earth and some of it out into space. Credit: A loose necktie on Wikimedia Commons. When sunlight reaches Earth, the surface absorbs some of the light’s energy and reradiates it as infrared waves, which we feel as heat.

Thermal Radiation - SpringerLink
网页2018年12月20日 · Thermal radiation, transmitted as electromagnetic wave energy, is a form of heat transfer generated by any matter having a temperature higher than absolute zero. Thermal radiation is one of the three basic forms of heat transfer (conduction, convection, and radiation), being a basic property of matter depending on its temperature.
