`2` moles of a monoatomic gas are expanded to double its initial volume, through a process `(P)//(V) =` constant. If its initial temperature is `300 K`, then which of the following is not true.A. `triangleT = 900 K`B. `triangleQ = 3200R`C. `triangleQ = 3600 R`D. `W = 900 R`

Answer» Correct Answer - B
`(P)/(V) constant = K`
PV = nRT
`rArr KV^2 = nRT`
`KV^2 = nRT`
`rArr (V_(1)^2)/(V_(2)^2) = (T_1)/(T_2)`
`V_1= V,V_2 = 2V,T_1 =300k`
`triangleW = intpdv`
`=overset(2v)underset(v)(int)kvdv =(3kv^2)/(2)`
`triangleQ = triangleu + trianglew`
