(II) A hot-air balloon achieves its buoyant lift by heating the air inside the balloon, which makes it less dense than the air outside. Suppose the volume of a balloon is 1800 m^3 and the required lift is 2700 N (rough estimate of the weight of the equipment and passenger). Calculate the temperature of the air inside the balloon which will produce the required lift. Assume that the outside air temperature is 0^∘ C and that air is an ideal gas under these conditions. What factors limit the maximu

Rain-cooled air near the core of a thunder storm sinks and then spreads out in front of the storm in a forward flank downdraft gust front (FIGURE 15-51 ). These gusts can vary from a cool breeze to a violent and damaging wind. Thunderstorms are extremely complex, but modeling air as an incompressible fluid can offer some insight. (a) Suppose 1.0 m^3 of rain-cooled air has a density of 0.835 kg / m^3, while the warmer air surrounding it has a density of 0.835 kg / m^3, while the warmer air surrou

Using a scale, a piece of alloy has a measured mass of 86 g in air and 73 g when immersed in water. Find its volume and its density. The apparent change in measured mass is due to the buoyant force of the water. Figure 13-7 shows the situation when the object is in water. From the figure, FB FT=m g, so FB=(0.086)(9.81) N-(0.073)(9.81) N=(0.013)(9.81) N But FB must be equal to the weight of the displaced water. or FB = Weight of water =( Mass of water )(g) =( Volume of water )( Density
