Q1-(20p) Fuel cell electric vehicles (FCEVs) are powered by hydrogen. They are more efficient than conventional internal combustion engine vehicles and produce no tailpipe emissions-they only emit water vapor and warm air. The vehicle consumes an average of 1kg of Hydrogen per 100km. The total range is targeted to be 800km. If a 700 bar pressure composite tank is used in the vehicle at ambient temperature; "You can get constant values from any source (For example; Ideal Gas Constant, Faraday constant etc.)" Calculate the internal volume of the tank in liters (in terms of water volume) using the following ways and interpret the results:: a- use ideal gas law b- use Van Der Waals EOS and c- use generalized compressibility d - use hydrogen
