This reaction absorbs a great deal of heat, cooling the material into which it is incorporated.

Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal.

This reaction absorbs heat from the surroundings, quickly lowering the pack's temperature.

Because it'll really increase chemical weathering of the rock, and all those reactions absorb CO2 from the air, so the air pressure is going to drop.

His reaction was to collapse "into an invalidism so intractable and absorbing that it must, of necessity, exclude any need but his own."

Since endothermic reactions absorb energy this means that energy must be used for the reaction to take place.

Then, one can imagine different mechanisms by which a reaction could absorb or emit energy, on a macroscopic scale.

This reaction absorbs huge quantities of energy, causing the star to collapse in the greatest cosmic explosion known.

A reaction may release or absorb energy, and a phase change may do the same, such as in melting and boiling.

The counsel's abrupt reaction absorbed him.
