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] $
