- Dry air is primarily composed of nitrogen. In a classroom demonstration, a physics instructor pours 2.00 L of liquid nitrogen into a beaker. After the nitrogen evaporates, how much volume does it occupy if its density is equal to that of the dry air at sea level? Liquid nitrogen has a density of 808 kg/m3.arrow_forwardHow many cubic meters of helium are required to lift a balloon with a 400-kg payload to a height of 8 000 m? Take He = 0.179 kg/m3. Assume the balloon maintains a constant volume and the density of air decreases with the altitude z according to the expression air = 0ez/8, where z is in meters and 0 = 1.20 kg/m3 is the density of air at sea level.arrow_forwardYou are making banana bread and the recipe calls for 3/4 cup of vegetable oil and one egg yolk. You measure out your oil in a measuring cup and then just toss the egg yolk into the oil before mixing with the dry ingredients. The egg yolk has a mass of 9.9 grams and floats with 71 % of its volume under the surface of the oil. You also know that the density of the oil is Poil 0.95 cm³ What volume of oil is displaced by the egg yolk? cm3 What is the total volume of the egg yolk? cm³ What is the density of the egg yolk? g cm3 Imagine the egg yolk was floating in a salt-water solution instead (Pwater = 1.04 % .). What percentage of the yolk would be submerged in water? cm³arrow_forward
