Chemistry

The specific internal energy of helium at 300 K and 1 atm is3800 J/mol, and the specific molar volume at the same temperatureand pressure is 24.63 L/mol. Calculate the specific enthalpy ofhelium at this temperature and pressure in units of J/mol.


At what rate (in units of kW) is enthalpy transported by astream of helium at 300 K and 1 atm with a molar flowrate of 250kmol/h?


The specific internal energy of a fluid is 200 cal/g. What isthe internal energy of 25 g of this fluid, in units ofcal?

If the fluid leaves a system at a flow rate of 3 g/min, atwhat rate, in units of cal/min, does it transport internal energyout of the system?
