How can the ideal gas law be used to estimate the lift capacity of a hot air balloon of a given volume and air temperature?

For a perfect gas: pv = RT where p is pressure, N/m2, Pa, or kPa v is specific volume, m3/kg. T is absolute temperature, ° K. R is the gas constant, J/kgK or kJ ... PV = nRT. Ideal ... n - Number of moles of gas. Remember, a mol of a substance is a unitless amount of particles of the substance. R - Ideal gas constant. PV = nRT. where P is the pressure, V is the volume, n is the number of moles of substance in that volume, R is a constant known as the "Universal Gas ... ... (n). The mathematical form of the Ideal Gas Law is: PV = nRT and n = m/MW. Where: P - pressure. V - volume. n - number of moles. T - temperature. m - mass. MW ... “P is proportional to N/V” (n = N/V = “number density”). Combining these, we ... PV = NRT. Where “R” is the gas constant, 0.082 L atm mole-1 K-1. P = (N/V)RT ... Jul 27, 2016 ... Just treat n, r and P as constants, i.e. think of it is a function, v of one variable v(T)=V(n,r,T,P). Share. ... PV = nRT, where R = universal gas constant calculated in various units. ... Number of Molecules Per Unit Volume. The ideal gas equation for n mole gases,. PV = ... Aug 28, 2020 ... Simply use cross-multiplication to solve for n. Since the equation is PV = nRT, divide both sides by the R & T and you end up with n = PV/RT. PV = nRT. Brings together gas properties. P*V is Proportional to T. Page 3. Ideal Gas Equation. P V = n R T. Universal Gas Constant. Volume. No. of moles. Apr 17, 2025 ... ... n • Formula- PV = nRT • R = gas constant = .0821 atm. liters mole. kelvin. Ideal gas law • The ideal gas law combines the pressure, volume ...
