Given is the graph between (PV)/T and P ...

Given is the graph between `(PV)/T` and P for 1 gm of oxygen gas at two different temperatures `T_(1) and T_(2)` Fig. Given, density of oxygen `= 1.427 kg m^(-3)`. The value of `(PV)//(T)` at the point A and the relation between `T_(1) and T_(2)` are respectively :

A

`0.256J//K` and `T_(1)ltT_(2)`

B

8.314 J/K and `T_(1)gtT_(2)`

C

8.314J/K and `T_(1)ltT_(2)`

D

0.256J/K and `T_(1)gtT_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`PV=muRT=(m)/(M)RTrArr(PV)/(T)=(m)/(M)R`
Real gas behave as idela gases at low pressure high temperature, so, `T_(1)gtT_(2)`
