Answer:
Explanation:
Since the transferred heat is equal to the change in the internal energy, the heat is proportional to the mass of the substance and the temperature change. The transferred heat also depends on the substance so that, for example, the heat necessary to raise the temperature is less for alcohol than for water. Hope that helps!:)

Explanation:
Compression vs Tension
Tension and compression are two concepts discussed in physics. Tension is a force, while compression is a phenomenon. Both these concepts play important parts in fields such as mechanical systems, automobile engineering, heat engines, material science, pendulums and various other fields. It is vital to have a proper understanding in tension and compression in order to excel in such fields. In this article, we are going to discuss what compression and tension are, their definitions, applications of compression and tension, the similarities between compression and tension and finally, the difference between compression and tension.
Answer:
Colloidal dispersion or emulsion
Explanation:
The colloid of a liquid in liquid (both dispersed phase and dispersion medium are liquids) is known as emulsion or colloidal dispersion.
We know that oil and water are immiscible liquids. In order to make them miscible we have have add emulsifying agents.
An emulsifying agent has a long non polar hydrocarbon chain (in general) and a polar head.
For example salts of fatty acids.
The polar head is hydrophilic and non polar tail is hydrophobic.
It causes the miscibility of the two polar and non polar liquids
Single Replacement
<h3>Further explanation</h3>
Given
Reaction
Mg(s) + 2 HCl(aq) → MgCl2 (aq) + H2 (g)
Required
Type of reaction
Solution
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
General formula :
A + BC ⇒ AC + B
Not all of these reactions can occur. We can use the activity series(the Volta series)
The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger the reductor)
