It forms shiny, homogeneous masses, quite insoluble in cold water and in salt solutions, but soluble in alkalies.
The calorimeter is surrounded by an air-jacket connected to a petroleum gauge which indicates any small change of temperature in the calorimeter, and enables the manipulator to adjust the supply of cold water to compensate it.
As an auxiliary to air cooling the stack may be cooled by a slow stream of water trickling down the outside of the pipes, or, in certain cases, cold water may be injected into the condenser in the form of a spray, w here it meets the ascending vapours.
The men sat huddled up trying not to stir, so as to warm the water that had trickled to their bodies and not admit the fresh cold water that was leaking in under their seats, their knees, and at the back of their necks.
When dropped very cautiously into cold water it dissolves into a clear solution.
Brown rods may also be buffed by sinking them in cold water which is heated to boiling point, and maintained at that temperature for the requisite period.
It is very hygroscopic and with cold water gives the oxide and hydrochloric acid.
The vapours pass through the inner tube, and the cold water enters at the end farthest from the distilling flask.
When the patient is very restless, so that cradling is impossible, a wet pack may be employed, a sheet wrung out of cold water being wrapped round him, and over this a blanket.
It slowly reacts with cold water to form phosphorous acid; but with hot water it is energetically decomposed, giving much red phosphorus or the suboxide being formed with an explosive evolution of spontaneously inflammable phosphoretted hydrogen; phosphoric acid is also formed.
