Notwithstanding these ingenious attempts to produce light by chemical action, the flint-and-steel retained possession of the field until a match was made that ignited by friction alone.
Luminous phenomena may be produced by various means--chemical action is a source of light; and, under several circumstances in which the laws of affinity are strongly exerted, a very intense luminous effect is produced.
Chemical action commences in the seed, the vital spark is kindled in the embryo, and under the impulsive force of some solar radiations the plant struggles into light and life.
Chemical action may be only due to the disturbance of some diffused principle; or it may be directly owing to some agency which is radiated at once from the sun.
We have learned that cells furnish current as a result of chemical action, and that the substance usually consumed within the cell is zinc.
In this case, chemical action is expended in heat rather than in the production of electricity and the liquid becomes hot.
In chemical action bromine is very similar to chlorine.
When sodium nitrate is treated with concentrated cold sulphuric acid, no chemical action seems to take place.
At the hands of Stahl and his school, the phlogistic theory, by exhibiting a fundamental similarity between all processes of combustion and by its remarkable flexibility, came to be a general theory of chemical action.
An arithmetical formula, useful, on many occasions, for ascertaining the proportion of constituents in a mixture, when they have undergone no change of volume by chemical action.
It is made of cast iron, about two inches thick in the belly and bottom; this strength being requisite because the chemical action of the materials wears the metal fast away.
But, in a chemical action such as the solution of gases, the nature of the impinging molecules plays, on the contrary, the most important part.
Chemical action in such cases appears necessary, although mechanical means, as percussion will produce heat.
We will only add, however, that until we can give a better theory, the effect in these instances may be attributed to chemical action, and with it, the change of caloric in the manner already mentioned.
The quantity of electricity he concludes is proportional to the amount of chemical action.
Thus he concludes that when the same quantity of electricity is caused to pass through a series of cells containing acidulated water, the electro-chemical action is independent of the size of the electrodes.
The name is misleading, since even in this attempt electricity is in no sense "stored," but a chemical action producing a current takes place in the machine.
In the other, illustrated by the case of chemical action, the separate effects cease entirely, and are succeeded by phenomena altogether different, and governed by different laws.
In the case of chemical action, for instance, the particles separate and form new combinations, often with a great visible disturbance of the mass.
Thus it is now thought that in the production of heat by friction, percussion, chemical action, etc.
In chemical action and in vegetable and animal life, the causal agents concerned are blended in their results in such a way that most of the qualities which they exhibited severally are lost, whilst new qualities appear instead.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "chemical action" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
