degassed

Finally, the degassed magma is pushed upward, filling the cone.

The raw material is mixed and degassed and then poured into the mold.

So the degassed hot water should freeze at a lower temp than the non-degassed cold water.

A dry and degassed adsorbent sample of known weight was enclosed in the adsorption cell.

Reactions of diazenes should employ degassed solvents to avoid radical reactions with oxygen.

All degassed helium is lost to space eventually, due to the average speed of helium exceeding the escape velocity for the Earth.

However, a degassed viscous lava or one which erupts somewhat hotter than usual may form a lava flow.

Oxygen-free (degassed) water is preferred for storage to prevent oxidation of the catalyst, which would accelerate its aging process and result in reduced catalytic activity.

Experiments have shown that siphons can operate in a vacuum, provided that the liquids are pure and degassed and surfaces are very clean.

Due to fire risks, solvent stills have largely been replaced by solvent columns in which degassed solvent is forced through an insoluble drying agent before being collected.

The presence of solute particles in the water should have the effect of decreasing its thermal conductivity, therefore making it take longer to freeze cold water than the relatively degassed hot water (your professor's view, I guess).

Conjugated dyes generally have a lifetime between 1-10 ns, a small amount of longer lived exceptions exist, notably pyrene with a lifetime of 400ns in degassed solvents or 100ns in lipids and coronene with 200ns.

The reaction is usually performed under inert atmosphere using dehydrated and degassed solvent, as oxygen causes the oxidation of the palladium catalyst and promotes homo-coupling of organic stannyl compounds, and these side reactions lead to a decrease in the yield of the desired cross-coupling reaction.

They consist of one or more upstream pipes, where the water is aerated while rising up, a degassing chamber where the aerated water is freed of gases and one or more downstream pipes where the vented, degassed water is pumped back into the hypolimnion.
