Volume has the same relationship with the number of particles than the pressure.
You can see it in the ideal gas equation: PV = nRT
As much as V and P are proportional to n.
Answer:
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

Answer:
All of the above.
Explanation:
In positive deviation from Raoult's Law occur when the vapour pressure of components is greater than what is expected value in Raoult's law.
When a solution is non ideal then it shows positive or negative deviation.
Let two solutions A and B to form non- ideal solutions.let the vapour pressure of component A is 
and vapour pressure of component B is 
.
= Vapour pressure of component A in pure form
= Vapour pressure of component B in pure form
=Mole fraction of component A
=Mole fraction of component B
The interaction between A- B is less than the interaction A- A and B-B interaction.Therefore, the escaping tendency of liquid molecules in mixture is greater than the escaping tendency in pure form.Hence, the vapour pressure of a mixture is greater than the initial value of vapour pressure.
,
Therefore, 
Therefore, the enthalpy of mixing is greater than zero and change in volume is greater than zero.
Hence, option a,b,c and d are true.
NaOH is hygroscopic
Explanation:
- A standard solution is a solution of known molarity or concentration.
- Standard solutions are used in determining the stoichiometric amount of desired species in an experiment.
- A solution of NaOH is not a standard solution because NaOH is hygroscopic in nature.
- By this, NaOH absorbs moisture from the atmosphere in considerable amount.
- This implies that one must find an air free environment to store and use the compound and accurately quantify it.
- This is why a solution of NaOH is standardize with a primary standard.
