Sentences with phrase «which absorb heat»

The point about heating (adding energy) vs warming (temperatures going up) is a very good one — it might help if the scientists involved with the major temperature series people look at (GISS, RSS, etc) also produced a global surface energy change index that accounted for things like melting ice, which absorb heat without raising temperatures.

The molecule will first use the heat energy in expansion and on cooling will again condense and sink because heavier, and it will cool when its heat expanded volume flows to colder air which absorbs the heat, the internal kinetic energy of vibration, which if strong enough will pass that heat to another colder (which is why visible light is not a thermal energy, it is not powerful enough to move a molecule of matter into vibration, it takes the bigger heat wave, longwave infrared, aka thermal infrared called that because it is the wavelength of heat)-- that is how convective heating warms the fluid gas air in a room, by circulation, in the rise and fall of molecules as they expand and condense, not by heat energy propelling molecules to hit other molecules..

Instead of sending sunlight directly to the solar cell, thermophotovoltaic systems have an intermediate component that consists of two parts: an absorber that heats up when exposed to sunlight, and an emitter that converts the heat to infrared light, which is then beamed to the solar cell.

Melting sea ice exposes dark ocean, which means that the planet absorbs more solar heat.

Trees perform three major climate functions: They absorb carbon, which they pull from the atmosphere, creating a cooling effect; their dark green leaves absorb light from the sun, heating Earth's surface; and they draw water from the soil, which evaporates into the atmosphere, creating low clouds that reflect the sun's hot rays (a mechanism known as evotranspiration that also leads to cooling).

As the climate changes, Southern Ocean upwelling may increase, which could accelerate ice shelf melting, release more carbon into the atmosphere and limit the ocean's ability to absorb heat and carbon dioxide from the atmosphere.

Instead of dissipating into space, the infrared radiation that is absorbed by atmospheric water vapor or carbon dioxide produces heating, which in turn makes the earths surface warmer.

The rest gets turned into radio waves or light, which turn into heat when they are absorbed by other surfaces.

Shivering and trying to warm the body by exercising only contribute to heat loss; the cold water absorbs the heat far more quickly than the body can create it and cools the extremities, which then cool the body's core.

This promises a huge improvement compared to current technology, in which the absorbed light energy is dissipated as heat to the crystal lattice, making the conventional excitation schemes extremely inefficient.

The results of the study could help improve monsoon prediction models, which usually use a constant value for sand particles» heat - absorbing ability.

Rhodium accelerates these reactions with an added boost of energy, which usually comes in the form of heat because it is easily produced and absorbed.

Instead, black carbon is expelled into the atmosphere combined with other compounds such as sulfates, which affect their heat - absorbing and reflective properties.

Another positive feedback of global warming is the albedo effect: less white summer ice means more dark open water, which absorbs more heat from the sun.

Earth's storm clouds are stopped about 20 kilometres up by a layer of warm air heated by ozone, which absorbs the sun's ultraviolet rays.

Hyperthermia (hyperpyrexia), in its advanced state referred to as heat stroke or sunstroke, is an acute condition which occurs when the body produces or absorbs more heat than it can dissipate.

Each dot absorbs and concentrates a laser's heat, which then flows through the underlying material as phonons.

The researchers heated a solution of molecules derived from fructose — the basic building blocks for their plastics — and molecules that can absorb light to make long chains that form the plastics, which appeared as pale brown solids.

The formation of a stratosphere layer in a planet's atmosphere is attributed to «sunscreen» - like molecules, which absorb UV and visible radiation coming from the star and then release that energy as heat.

We also find heat sloshing around the world's oceans, which absorb 93 quadrillion watts of the sun's energy — a hundred thousand times more power than could be produced by all the power plants in the United States put together.

Pete Best writes: > It seems that the oceans have absorbed much heat > over the summer but have relased it into the > atmosphere which has caused the ocean to freeze > quickly and oddly
