Two high pressure rigid tanks are connected by a channel. At first, tank A contains 30kg water with TA=300K. Tank B contains 50kg of water with TB=400K. Water in the two tanks is allowed to mix adiabatically (no heat loss or gain to the surroundings). Assuming that the specific heat of water is constant, the equilibrium temperature of the mixture is = ?
