Physical properties include: appearance, texture, color, boiling point, melting point, ect.
Answer: Option (c) is the correct answer.
Explanation:
Polar molecules are defined as the molecules that chemically combine together and have partial opposite charges.
For example, 
is a polar molecule as due to the difference in electronegativity of hydrogen and oxygen atom there is partial positive charge on hydrogen atom and partial negative charge on oxygen atom.
On the other hand, molecules which are neutral in nature are known as non-polar molecules. A non-polar molecule is formed by equal sharing of electrons.
For example, 
is a non-polar molecule.
As in a large polar molecule, there will be greater force of attraction between the oppositely charged ions due to large surface area. Hence, large amount of heat needs to given in order to break the bonds.
Therefore, we can conclude that a large polar molecule will have the highest boiling point.
Answer:
A. Provide both heat and power to homes
Answer:
Car oil and vegetable oil will mix well with gasoline
Car oil and vegetable oil will not mix with water.
Explanation:
Car oil and vegetable oil will mix well with gasoline
Car oil and vegetable oil will not mix with water.
This is because of the rule of solubility. According to this rule, like substances will only dissolve like substances. In essence, a polar compound will only dissolve another polar compound. A non-polar compound will dissolve only in a non-polar solvent.
Water is polar and oil is non-polar. The cannot mix.
Gasoline is non-polar and will dissolve oil which is also non-polar .
The answer to this would be d. Precipitation patterns .
