1.	The kinetic energy per kg of nitrogen molecules at 175^(@)C` is (Molecular weight of nitroegn 28 and R=3820 J/k mole K)A. `19.968xx10^(6)J`B. `1.783xx10^(5)J`C. `1.9968xx10^(5)J`D. `1.678xx10^(5)J`
Answer» Correct Answer - C `K.E_(2)//kg=(3)/(2)(RT)/(M)=(3)/(2)xx(8320xx448)/(28)` `=(3xx8320xx224)/(28)` `=3xx8320xx8=24xx8320=199680`
