The basis of the quantum mechanical model of an atom is

The ratio of $C_p$ and $C_v$ of a gas $'X'$ is $1.4$. The number of atoms of the gas $'X'$ present in $11.2 \ L$ of it at $NTP$ will be:

Which of the following cylindrical rods will conduct the most heat when their ends are maintained at the same steady temperatures?

The term that accounts for intermolecular force in Vander Waals equation for non-ideal gas is:

In the $CGS$ system,the magnitude of the force is $100 \text{ dynes}$. In another system where the fundamental physical quantities are kilogram,meter,and minute,the magnitude of the force is:

Two capacitors $C_1$ and $C_2$ are charged to $120 \ V$ and $200 \ V$ respectively. It is found that by connecting them together,the potential on each can be made zero. Then:
