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
