A CNG $($compressed natural gas$)$ tank for a mass transit bus is being pressure tested with nitrogen gas to confirm its strength and its ability to hold the CNG without leaking. The test was started with an initial temperature of $31$oC and a $1\mathrm{.}1$ MPa $($gage pressure$)$ reading. At the end of the shift, the temperature had dropped to $25$oC with an actual pressure to $\mathrm{.}95$ MPa $($gage pressure$)$ reading. $$
