Define the Tea in Thermos?
One liter of tea at 90° C is poured keen on a vacuum-insulated container (thermos). The surface area of the thermos walls A=600 cm2. The volume among the walls is pumped down to Po~ 5.10-6 atm pressure (at room temperature). The emissivity of the thermal and the walls capacity of water C = 4.2.103 J/kg K. ignore the heat leakage through the stopper, estimate the
