- Answer number 4.arrow_forwardThe pressure of 200mols of ideal gas in a hot air balloon is 500,000Pa. The mass of the balloon itself is 1kg. If the temperature of the hot air is 400K and the mass density of the cold air is 1kg/m3, what is the total force on the balloon? Recall that the buoyant force is the weight of the cold air displaced by the balloon. (hint: remember the two forces on the balloon are the weight of the balloon and the upward buoyant force.) Use R-10 J/molk, g=10 m/s², and ignore the weight of the air in the balloon. 4 O 3N O 10N O 6N O 4N O 14Narrow_forwardExample: A water tank with a wall thickness of 10 mm and a water temperature of 90 "C.)
