Question

A 5g droplet of liquid nitrogen is enclosed in a 50mL tube which is sealed at very low ressure. When the tube is warmed to 35?C, the nitrogen pressure in the tube is (molecular weight of nitrogen = 28, R = 8.3 J/mol K)

• A. $\text{9}.\text{13}\times \text{1}{0}^{\text{3}}\text{N}/{\text{m}}^{\text{2}}$
• B. $\text{18}.\text{26 N}/{\text{m}}^{\text{2}}$
• C. $\text{2}.\text{25}\times \text{1}{0}^{\text{3}}\text{min}$
• D. $\text{3}.\text{97}\times \text{1}{0}^{\text{3}}\text{min}$

Answer 1

Answer: (C)

$\text{5}.\text{25}\times \text{1}{0}^{\text{3}}\text{min}$ $\left[\text{FL}{\text{T}}^{-\text{2}}\right]$ $\left[\text{F}{\text{L}}^{\text{2}}{T}^{-\text{2}}\right]$ $\left[\text{F}{\text{L}}^{-\text{1}}{\text{T}}^{\text{2}}\right]$
