A process in which no work is transferred is sometimes called adynamic.

Symptoms of adynamic ileus include:

Adynamic transfer of energy as heat can be measured empirically by changes in the surroundings of the system of interest by calorimetry.

Batke M, Cappell MS. Adynamic ileus and acute colonic pseudo-obstruction.

Transcortical motor aphasia (also known as Adynamic aphasia and Extrasylvian motor aphasia)

Common side effects include: Nausea and vomiting, hypocalcemia, and adynamic bone disease if iPTH levels drop below 100pg/mL.

Ileus (adynamic or paralytic ileus) is a type of bowel obstruction that occurs when the intestines stop moving normally even though there is nothing blocking them.

Transcortical Motor Aphasia (TMA), also known as adynamic aphasia and extrasylvian motor aphasia, results from an injury to the anterior superior frontal lobe.

When the system evolves with transfer of energy as heat, without energy being transferred as work, in an adynamic process, the heat transferred to the system is equal to the increase in its internal energy:

This account first considers processes for which the first law is easily verified because of their simplicity, namely adiabatic processes (in which no heat is transferred) and adynamic processes (in which no work is transferred).
