The laws show: PV=nRT Where P=Gas Pressure in system (kg s^(-2) m^(-2) ) V=volume occupied by gas (m^3 ) n=number of moles of gas R=Universal Gas Constant (8.314 J K^(-1) mol^(-1) T=Absolute temperature of has (K) Considering an ideal hot air balloon of 100% efficiency, an equation can be derived from the gas laws to predict the payload (weight a balloon can carry) and analyze trends in the factors affecting flight. ... Although literature values exist, it is unlikely to be of equal magnitude as the balloon system is not 100% efficient. ... Energy Density of Fuels Energy Density i...
