Water in an electric teakettle is boiling. The power absorbed by the water is 1.00 kW. Assuming the pressure of vapor in the kettle equals atmospheric pressure, determine the speed of effusion of vapor from the kettles spout if the spout has a cross-sectional area of 2.00 cm2. Model the steam as an ideal gas.
