So, this is an application of Avogadro's law (which is derived from the ideal gas law or PV = nRT where P is the gas pressure, V is the volume occupied by the gas, n is the moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin). A helium balloon ride lifts up passengers in a basket. You can find this image quite interesting: You are exactly correct that it is a matter of atmospheric pressure decreasing at a rate great enough to overcome the contraction due to decrease in temperature. Steps to complete the problem: List all of the variables given. Volume of the selected item is calculated using its density and entered weight. V &= \frac{m_\text{payload}}{\rho - \frac{PM_h}{RT}} \\ I start from the Buoyancy Formula: $$n = \frac{PV}{RT} = \frac{101 \times 10^3 \times 4.71}{8.314 \times 288.2} = 199\text{mol}.$$. A ballon filled with 1lb of helium weighs 1lb+ the ballon. As important. The volume of the balloon is 0.030m ^3. Both pressure and temperature will increase -- but temperature does not rise so fast that the volume will stay constant!). Which differs slightly from our previous result based on the $30$km buoyancy calculation due to inaccuracies in the air density value at $30$km. If The speed of the cart, 1. For a better experience, please enable JavaScript in your browser before proceeding. 15 cu ft (.425m3) 3-5 days. Using the atmospheric data for sea level and a payload mass of $5\text{kg}$ (seems somewhat reasonable), the volume comes out as, $$V = \frac{5}{1.23 - \frac{101\times 10^3 \times 0.004}{8.314 \times 288.2}} = 4.71\text m^3.$$.
