The investigation using solid and liquid water to show that thermal energy is not the same as temperature is:
- Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.
<h3>What is the response to the experiment above?</h3>
The response is No, because the lake is known to have a lot more particles than the glass of water and so they will not have the same thermal energy.
Note that the temperature is seen as the an average and thermal energy is seen to be the total. A glass of water can be able to have the same temperature as what we call Lake Superior, but the lake has a lot of thermal energy due to the fact that the lake has a lot of water molecules.
So the investigation using solid and liquid water to show that thermal energy is not the same as temperature is Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.

A. Tolerance range is different for different organisms.
Fatty acids are composed of hydrocarbon chains and a carboxyl group.
<h3>What are Fatty acids ?</h3>
Fatty acids are the building blocks of the fat in our bodies and in the food we eat.
During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood.
Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.
Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end.
It is that carboxyl group that makes it an acid (carboxylic acid).

all of those can be determined by units
a) A combound which contains only Carbon and Hydrogen. There are covalent bonds between atoms. Hydrogen form one single bond and Carbon forms four covalent bonds. Carbon bonds can be single, double or triple bonds.
All hydrocarbons are organic compounds, but organic compound can include atoms of other elements.
b) Alkyne has a covalent triple bond between two carbon atoms. Simplest alkyne is ethyne HCCH.
b) Alkane contains only Carbon and Hydrogen and there are single bonds
between atoms. Simplest alkane is methane CH4.
c) An alkene has one double bond between Carbon atoms. Simplest
alkene is ethene H2C=CH2.
