A closed volume of 1 m3 of air (at sea level) is heated from 20°C to 400°C. Use the values for specific heat (cv =20.786 J/molK , cp= 29.1006 J/molK) and the specific gas constant R=8.31446 J/molK

a) How much heat must be added to the gas to cause the temperature change?

b) What is the pressure change in the gas?

c) What is the change of enthalpy in the gas?

d) What is the change of enthalpy due to the pressure change?
