What are some examples of a thermodynamic system where no work is done on the system, but the first law is applied?
Work in thermodynamics is based around volume. Would that mean if the system's volume decreased, then work is done by the system instead of on the system?
As an example: If heat is applied to ice and it melts, it's volume will decrease. Despite heat being added to the system does the decreased volume mean work was not done on the system?
