Argon in a light bulb is at 90 kPa and heated from 20°C to 60°C with electrical power. Do not consider any radiation, nor the glass mass. Find the total entropy generation per unit mass of argon.
C.V. Argon gas. Neglect any heat transfer.
Since there was no heat transfer but work input all the change in * is generated by the process (irreversible conversion of W to internal energy)
