As the slab plunges yet deeper, dehydration
reactions release water, which at such great pressure and temperature exists as a supercritical fluid that can drift through materials like a gas and dissolve them like a fluid.
Not exact matches
The smell that's
released and your ensuing
water works are a result of a chemical
reaction taking place.
Hotter
water can help to
release soil by increasing the cleaning action and chemical
reactions.
The rods absorb light, which
releases electrons and sets in motion a chain
reaction that ends with the
water in the beaker
releasing its oxygen, as desired.
A biochemistry major, Gazzaley had planned to put a chunk of sodium metal into a lake behind campus to make it fizz — a large - scale version of the classic junior high school lab experiment in which adding a pinch of potassium to
water creates a spark as the chemical
reaction releases energy.
These are intended to slow the flow of
water through the wreck, minimising the
release of plutonium and slowing chemical
reactions that cause corrosion.
But when
water corrodes uranium, the
reaction also
releases hydrogen.
Enriched uranium oxide is formed into rods and
water is used both as a coolant, flowing through the reactor core to transfer heat away, and as a moderator, slowing down neutrons
released by fission so that they promote further nuclear
reactions.
Hydration
reactions along the subducting plate are thought to carry
water deep into the Earth, and dehydration
reactions at greater depths
release fluids into the overlying mantle that promote melting and volcanism.
The
water around the reactor core serves as three things: a neutron moderator, meaning it slows down the fast neutrons
released during fission, which then sustain the chain
reaction; a cooling agent; and a radiation shield.
At the center of the Sun, where its density reaches up to 150,000 kg / m3 (150 times the density of
water on Earth), thermonuclear
reactions (nuclear fusion) convert hydrogen into helium,
releasing the energy that keeps the Sun in a state of equilibrium.
I believe that
reaction takes much longer than bubbles require to reach the surface; the methane
released in these bubble sites or in rapid events like underwater landslides) either dissolves in
water or reaches the atmosphere in a matter of minutes, according to what was posted here earlier.
One of the reasons for the lag is the delayed
reaction of the surface
waters of the oceans to the absorption of heat and it's ultimate contribution by
releasing this heat back to the atmosphere.
Once the
reaction is underway, the energy
released sustains the
reaction and can be harnessed to generate electricity or to heat hot
water for bathing.
LIA wasn't GLOBAL cooling; but colder in Europe, north America — because Arctic ocean had less ice cover - > was
releasing more heat / was accumulating - > radiating + spreading more coldness — currents were taking that extra coldness to Mexican gulf — then to the Mediterranean — because Sahara was increasing creation of dry heat and evaporating extra
water in the Mediterranean — to top up the deficit — gulf stream was faster / that was melting more ice on arctic also as chain
reaction — Because Mediterranean doesn't have enough tributaries, to compensate for the evaporation deficit.
My first
reaction is that the condensation of
water vapor — removes a little gas from the air —
releases relative to the that volume of gas a huge amount of latent heat
Combustion
reactions break these bonds,
releasing energy, as well as carbon dioxide and
water vapor as byproducts.
As CO2 rises, some enters the oceans and through basic chemical equilibrium
reactions involving the dissociation of its hydrated form, carbonic acid to
release hydrogen ions, lowers the pH of the
water (i.e., raises the hydrogen ion concentration).
Then a lake Nyos type event where the the
water got overturned and the suddenly supersaturated
water formed mathane bubbles, driving further circulation and methane
release in a chain
reaction.
