An insulated container of gas has two chambers separated by an insulating partition. One of the chambers has volume V_(1) and contains ideal gas at pressure P_(1) and temperature T_(1). The other chambers has volume V_(2) and contains ideal gas at pressure P_(2) and temperature T_(2). If the partion is removed without doing any work on the gas, the final equilibrium temperature of the gas in the container will be

Answer»

<P>`(T_(1)T_(2)(P_(1)V_(1)+P_(2)V_(2)))/(P_(1)V_(1)T_(2)+P_(2)V_(2)T_(1))`
`(P_(1)V_(1)T_(1)+P_(2)V_(2)T_(2))/(P_(1)V_(1)+P_(2)V_(2))`
`(P_(1)V_(1)T_(2)+P_(2)V_(2)T_(1))/(P_(1)V_(1)+P_(2)V_(2))`
`(T_(1)T_(2)(P_(1)V_(1)+P_(2)V_(2)))/(P_(1)V_(1)T_(1)+P_(2)V_(2)T_(2))`
