Vapour pressure is the pressure exerted by vapour molecules over a liquid surface.
The vapour pressure is a property
a) inter molecular forces: higher the inter molecular forces lower the vapour pressure, In this case we have taken same liquid (milk) hence in all case the inter molecular forces will be same.
b) Temperature: higher the temperature higher the kinetic energy of molecules and more the tendency of liquid molecules to convert to vapor phase.
The vapor pressure will be independent of the container being closes or open.
Thus vapor pressure will be high in Bowl B which is uncovered, and the milk is warmer than room temperature, as it has higher temperature than all other bowl of milk.
Explanation:
a. Average kinetic energy is directly proportional to absolute Kelvin temperature of a gas.
Yes
b. There are no attractive forces and repulsive forces between gas molecules.
Yes
C. Atoms are neither created nor destroyed by ordinary chemical reactions.
No
d. The volume occupied by all of the gas molecules in a container is negligible compared to the volume of the container
Yes
The kinetic molecular theory is one of such theories used to explain the forces between molecules and the energy they posses.
According to the theory;
- The temperature of gas is proportional to the average kinetic energy.
- Molecules are independent of one another and the force of attraction and repulsion between them is negligible.
- volume occupied by gases is negligible compared to the volume of the container.
Law of conservation of matter states that "atoms are neither created nor destroyed by ordinary chemical reactions".

A. The concentration is in mol/L
The elements are listed in order of increasing the atomic number. Its the number that is the number of protons in the nucleus of an atom.
