A measure of the kinetic energy of particle motion within a substance is _____.
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
It is known that energy obtained by an object due to its motion is known as kinetic energy. Whereas an energy obtained by an object due to its position is known as potential energy.
For example, when water is heated then bond between its molecules starts to break and therefore, molecules start to move as they tend to gain kinetic energy due to increase in temperature.
Also, it is known that K.E =
where k = boltzmann constant
T = temperature
Hence, kinetic energy is proportional to temperature. So, more is the increase in temperature more will be the increase in kinetic energy.
Thus, we can conclude that a measure of the kinetic energy of particle motion within a substance is temperature.

Answer : The sketch of two amino acids side by side are shown below.
Explanation :
Amino acid : Amino acid are the acid that contains two functional groups which are carboxylic group, and ammine group,
.
When the two or more that two amino acids join together with the help of peptide bond, they produces polypeptide chain or protein.
The bond present between the two amino acid is called a peptide bond.
The peptide bond is a chemical bond that is formed between the two molecules when the nitrogen of one amino acid react with the carbon of another amino acid by releasing a water molecule.
Hence, the sketch of two amino acids side by side are shown below.
