SOLID-STATE VERSUS THERMIONIC DEVICES: When a metal or carbon filament is heated to high temperatures electrons are emitted from the filament.

Note that the intensity versus wavelength plot for the radiation emitted from the hole connecting the cavity to the outside has the same shape.

The carbon dioxide emitted from burning biomass will not increase total atmospheric carbon dioxide if this consumption is done on a sustainable basis (i.

Some of the radiation is eventually emitted into space, because that's one direction.

A tonne of CO2 not emitted in Europe is just as good as a tonne of CO2 not emitted in Victoria.

The radiation eventually reaches the top of the atmosphere and is emitted into space (the only way it can leave).

The radiation--or, rather, radiation at certain frequencies--eventually makes it into the stratosphere and is absorbed and emitted in all directions by molecules of CO2, H20, and CH4.

Some of the radiation is eventually emitted into space, because that's one direction.

We can not only reduce the gases that are emitted to the atmosphere but also increase the gases that are taken out of the atmosphere.

When people see volcanic eruptions on television and it's awesome, and it's very easy for people to imagine that huge amounts of CO2 are being emitted to the atmosphere.

Carbon dioxide (CO 2) is the principle greenhouse gas emitted as a result of human activities such as the burning of coal, oil, and natural gases.

It is defined as the power emitted per unit surface area per unit solid angle.

The shorter-lived each kind of radioisotope in the decay series, the more radiation it emits per unit mass.

These emit next to zero CO2 and produce usable power 24/7.

The sign of this process is an unpleasant smell being emitted through the holes.

Gamma rays are often emitted with alpha or beta radiation also, as the nucleus decays to a less excited state.
