When this happens, the carbon atoms are said to be in solution, or mixed with the iron, forming a single, homogeneous, crystalline phase called austenite.

When this happens the carbon atoms will no longer be soluble with the iron, and will be forced to precipitate out of solution, nucleating into the spaces between the crystals.

When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable.

When the iron tip oxidises and burnt flux accumulates on it, solder no longer wets the tip, impeding heat transfer and making soldering difficult or impossible ; tips must be periodically cleaned in use.

: When he wished to print, he took an iron frame and set it on the iron plate.

When hit, even iron armour was quite pierced through.

When the metal had cooled and hardened, the smaller ingots ( the pigs ) were simply broken from the much thinner runner ( the sow ), hence the name pig iron.

When the hotter sections of the discs reach extremely high temperatures ( 1200 – 1300 degrees Fahrenheit ), the carbon within the cast iron of the disc will react with the iron molecules to form a carbide known as cementite.

When rebuilt around 1831, this was replaced by a wrought iron backhead and throatplate, with a drum wrapper ( now missing ), presumed to be of copper, between them.

When the partial pressure of is reduced, for example when a can of soda is opened, the equilibrium for each of the forms of carbonate ( carbonate, bicarbonate, carbon dioxide, and carbonic acid ) shifts until the concentration of in the solution is equal to the solubility of CO < sub > 2 </ sub > at that temperature and pressure.

When pH is too high, the concentration of hydrogen ions in the blood is too low, so the kidneys excrete bicarbonate ( HCO < sub > 3 </ sub >< sup >−</ sup >).

When two miscible liquids are brought into contact, and diffusion takes place, the macroscopic ( or average ) concentration

When inspired air contains CO levels as low as 0. 02 %, headache and nausea occur ; if the CO concentration is increased to 0. 1 %, unconsciousness will follow.

When the hailstone moves into an area with a high concentration of water droplets, it captures the latter and acquires a translucent layer.

When it is present at a much higher concentration, it also binds to OR3, inhibiting transcription from P < sub > RM </ sub >, thus regulating its own levels in a negative feedback loop.

( ii ) When concentration of the ions is very high, the presence of charges on the ions appreciably effects the equilibrium.

When they encounter an infection site the particles gain a positive charge provoked by the slightly acidic environment at the infection sites, allowing them to bind to the negatively charged bacterial cell walls and release antibiotics at locally high concentration.

When probenecid and penicillin are administered together, probenecid competitively inhibits the excretion of penicillin, increasing penicillin's concentration and prolonging its activity.

When a neurotransmitter is released at a synapse, it reaches its highest concentration inside the narrow space of the synaptic cleft, but some of it is certain to diffuse away before being reabsorbed or broken down.

When the endpoint of the reaction is reached, the volume of reactant consumed is measured and used to calculate the concentration of analyte by

When the diode is forward biased, the injected carrier concentration is typically several orders of magnitude higher than the intrinsic level carrier concentration.

When the Buchenwald camp was evacuated, the SS sent the male prisoners to other camps, and the five-hundred remaining women ( including one of the secret annexe members who lived with Anne Frank, " Mrs. van Daan ", real name Auguste van Pels ) were taken by train and on foot to the Theresienstadt concentration camp and ghetto in Protectorate of Bohemia and Moravia.

When the rate of synthesis of ketone bodies exceeds the rate of utilization, their concentration in blood increases, this is known as ketonemia.

When the product dissociates the concentration of B is equal to q / p times the concentration of A.

When Schultz, who is empathetic to the Jews, voices his objection to the pogrom, Hynkel denounces Schultz as a supporter of democracy and a traitor, and orders him placed in a concentration camp.

When the ghettos were liquidated his family was sent to the Auschwitz concentration camp.

They were, like those babies, nearly dead from hunger ..." When Field Marshal Montgomery wanted to allot each German citizen a guaranteed diet of only 1, 000 calories a day and justified this by referring to the fact that the prisoners of the Bergen-Belsen concentration camp had received only 800, Gollancz wrote about starvation in Germany, pointing out that many prisoners never even received 1, 000 calories.

When she refuses, he uses force: he breaks her concentration and terrifies her by throwing her out of the airplane, catching her with the airplane, and he uses this to kiss her.

When ketone bodies are measured by way of urine concentration, acetoacetic acid, along with beta-hydroxybutyric acid ( BHB ), and acetone, is what is detected.

When performing calculations regarding the reacting of one or more aqueous solutions, one generally must know the concentration, or molarity, of the aqueous solutions.

When the oceans contain a relatively high proportion of magnesium compared to calcium, aragonite is more stable, but as the magnesium concentration drops, it becomes less stable, hence harder to incorporate into an exoskeleton, as it will tend to dissolve.
