What happens to a gas flowing through a pipeline at a volumetric flow rate of $2\mathrm{.}5$m$^2/$min$.$ The temperature is maintained at $300\backslash$deg C and the pressure is $2\mathrm{.}00$ atm.

If the pressure is decreased to $1$ atm while still having the same temperature.

Explain how the change in pressure affects the volumetric, mass and molar flow rates.
