Reference words are words which are used to refer to something which is mentioned elsewhere in the text, usually in a preceding sentence. The most common type is pronouns, such as ‘it’ or ‘this’ or ‘these’. Study the previous example again. This time, the reference words are shown in bold. Cohesion is an important feature of academic writing.
What is the difference between cohesion and adhesion?
Cohesion: Cohesion is the cause for the formation of water droplets on the surface tension of a liquid. Adhesion: Adhesion is the cause for the spreading of a liquid on a solid surface. Adhesion and cohesion are two types of attraction forces that occur between molecules.
Which is a key feature of cohesion and coherence?
The second key feature is reference words. The third one is transition signals. The fourth is substitution. The final important aspect is ellipsis. The words it, which and these are reference words. The first two of these, it and which, both refer to ‘cohesion’ used in the preceding sentence.
Which is the final aspect of the word cohesion?
The final important aspect is ellipsis. In this example, the word cohesion is used several times, including as a verb ( coheres ). It is important, in academic writing, to avoid too much repetition, so using different word forms or synonyms is common.
What is the difference between adhesion and cohesion?
The defining feature is that adhesion occurs between two different substances. For example, the adhesion of water molecules to the plastic beaker causes them to cling at a higher level around the edges. Cohesion is the mutual attraction between like molecules that causes them to stick together.
How are cohesion and adhesion forces related to settling?
For example, if cohesion forces between the water molecules are stronger than that of the adhesion forces between them, then the individual molecules will attract towards each other thus resulting in settling.
What is the difference between cohesion and attraction?
Cohesion is the attraction force between molecules of the same substance. It is a mutual attraction between molecules. This attraction force causes the molecules to stick together. Cohesive forces are intermolecular forces since these forces can be found between the molecules of the same substance.
Which is an example of cohesion in water?
For example, if cohesion forces between the water molecules is strong than that of the adhesion forces between them, then the individual molecules will attract towards each other thus resulting to settling.
