Having an issue relating specific volume to the PV = nRT ideal
gas law, i believe i assume n=1 or cut it out completely but for V
do i somehow use the Specific gas constant to get the mass of the
gas in order to find the V value to use in the ideal gas law
instead of just using specific volume? For each gas is R in
the ideal gas law the universal gas constant or the specific gas
constant for each individual gas? If you could do the
first row as an example I should be able to get the answers i need
to finish the rest of the table, Im just stuck on those
issues.
2. Fill in the following table using the ideal gas law. Gas Temperature [°C] Pressure [kPa] Specific Volume [mº/kg] 1.50 Specific Gas Constant [kJ/kg K] Air 100.00 Air 200.00 0.50 Helium 50.00 30.00 Helium 25.00 100.00 Nitrogen 700.00 290.00 Nitrogen 25.00 100.00
