B) E_k(g) > E_k(l); E_p(g)

Pentane, C₅H₁₂, boils at 35°C. Which of the following is true about kinetic energy, E_k, and potential energy, E_p, when liquid pentane at 35°C is compared with pentane vapor at 35°C?

A) E_k(g) < E_k(l) ; E_p(g) $\approx$ E_p(l)
B) E_k(g) > E_k(l) ; E_p(g) $\approx$ E_p(l)
C) E_p(g) < E_p(l) ; E_k(g) $\approx$ E_k(l)
D) E_p(g) > E_p(l) ; E_k(g) $\approx$ E_k(l)
E) E_p(g) $\approx$ E_p(l) ; E_k(g) $\approx$ E_k(l)
