Not necessarily.
<h3>Explanation</h3>
Isomers might differ in polarities. They will end up with different physical properties such as melting points.
Example:
- 1,2-dichlorobenzene has a melting point of around -18 ~ -17 degrees celsius. (SynQuest)
- 1,4-dichlorobenzene (with two chlorine opposite to each other on a benzene ring) has a melting point of 52 ~ 54 degrees celsius. (SynQuest)
Both 1,4- and 1,2-dichlorobenzene contains two chlorine atoms connected to a benzene ring. The two molecules are structural isomers.
The two chlorine atoms are adjacent to each other in the 1,2 isomer. The molecule is asymmetric and polar.
The two chlorine align with an axis of symmetry in the 1,4 isomer. The molecule is symmetric. The dipoles would cancel out to produce a nonpolar molecule.
Dipole-dipole interactions are typically stronger than <em>induced</em> dipole<em> </em>in isomers. As a result, the 1,2 isomer has a higher melting point.
Answer:one object to speed up (gain momentum) and the other object to slow down (lose momentum).

Answer: Volume of 1g of pure gold 
Given;
Density of a pure gold=19.3 
Mass of a pure gold =1g
To find:
Volume of 1g of pure gold
Solution:
According to the formula,
Density= Mass/Volume
Where 
=density of pure gold
m=mass of pure gold
v=volume of pure gold
From the above equation volume can be calculated as
Substitute the values of mass and density value in the above equation
Result:
Thus the volume of 1g of pure gold is
