The figure shows a

p V

diagram for

8.3 \mathrm {~g}

of ideal nitrogen gas

\mathrm { N } _ { 2 }

in a sealed container. The temperature of state 1 is

59 ^ { \circ } \mathrm { C }

, the atomic mass of the nitrogen atom is

14 \mathrm {~g} / \mathrm { mol }

, and

R = 8.31 \mathrm {~J} / \mathrm { mol }

- K. What are (a) pressure

p _ { 1 }

and (b) temperature

T _ { 2 }

?
