Question

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.

Answer 1

C.V. Argon gas. Neglect any heat transfer.

Since there was no heat transfer but work input all the change in s is generated by the process (irreversible conversion of W to internal energy)
