Question

In ideal conditions, $\frac{\text{PV}}{\text{T}}$ is ______ for fixed mass of the gas.

• A. independent of the gas
• B. constant
• C. always varying
• D. zero

Answer 1

The correct option is B constant

For a fixed number of moles ($\text{n}$) for a gas, in ideal conditions, $\frac{\text{PV}}{\text{nT}}=\text{R}$.

where, $\text{P, V,}$ and $\text{T}$ refer to pressure, volume, and temperature of the gas respectively.

The values for $\text{R}$ usually used are $8.314\text{J}{\text{mol}}^{-1}{\text{K}}^{-1}$.
