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:
6.Given,
Final Velocity =60m/s
Initial Velocity= 0
Time=10 sec
A=?
A=Final Velocity- Initial Velocity/time
=60-0/10
=60/10
=6m/s ans.
Explanation:
Acceleration = Final Velocity - Initial Velocity/Time
By using this Formula we can calculate Acceleration.

Mass is always conserved in a physical change. Energy may be released or absorbed when a substance changes from one physical state to another. In a chemical change, a chemical reaction yields a completely new substance. A substance's particles are changed during a chemical reaction.
