Question 12

An engineer is testing the pressure-volume relationship of a nitrogen gas buffer inside a cryogenic storage system. The system maintains the nitrogen at a constant temperature of 77 K.

The engineer's experimental measurements are recorded in Table 1.

Table 1

Pressure, $P$ ( $atm\text{atm}$ )	Volume, $V$ ( $L\text{L}$ )	$\times V$ ( $L⋅atm\text{L}\cdot\text{atm}$ )
1.5	8.05	12.08
2.0	5.92	11.84
2.5	4.84	12.10
3.5	3.41	11.94
4.0	3.02	12.08

Use the data in Table 1 to estimate the volume of the gas buffer when the pressure is $atm3.0\text{ atm}$ .
