Confusion about the work done by an ideal gas

[QUOTE="Chandra Prayaga, post: 6047661, member: 6922"] 1. If the external pressure is constant, and you want to move the piston quickly, then there must be an internal pressure which is greater than the external pressure. This gives rise to a non-quasistatic process, which blows the piston outwards. In general, it is not possible to calculate the work done by the gas. 2. Zero work is done if the gas expands into a vacuum. This is also a non-quasistatic process. [/QUOTE]
