An ideal gas has a constant volume specific heat cv as a
function of temperature. Find the
change in internal energy and enthalpy if the gas is heated from a
temperature of 300K to 600K.
cv(T) = 716.66 + 0.4T + 0.000667T2 J/kg.K
Also, sketch the constant pressure specific heat as a function
of temperature and mention the
point T = 400K on the cp – T diagram. Assume that the gas constant
of the given ideal gas is
286.9 J/kg.K.

For the following, assume air is an ideal gas with constant
specific heats at 300K. Find the work and heat transfer and state
whether they are into or out of the air.
In an open system, air is heated at constant pressure from 27°C,
400 kPa to 500K.
w = 0 kJ/kg, q = 201 kJ/kg
In a closed system, air is heated at constant pressure from
27°C, 100 kPa to 500K.
w = 57.4 kJ/kg, q = 201 kJ/kg
