In a certain problem, we have a gas under a thermally isolating piston, yet somehow the author says that, due to this, the internal energy of the gas i am trying to find an error in the reasoning, and i am not quite sure what does thermally insulated mean.
A Vessel Whose Walls Are Thermally Insulated. An insulated beaker with negligible mass contains 0.250 kg of water at 75.0$^\circ$c. How many grams of steam must condense inside the vessel (also at atmospherics pressure) to raise the temperature of the system to 21.0 c?

The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water. Then the air from the vessel is pumped out adiabatically. The walls of the left ventricle are three times as thick as the walls of the right one.
The blood vessels are supplied with nerves.
An insulated beaker with negligible mass contains 0.250 kg of water at 75.0$^\circ$c. The outlet of a tube leading from a boiler in which water is boiling at atmospheric pressure is inserted into the water. The distance between the waterline and the main deck is the vessel's freeboard. The insulating capability of a material is measured as the inverse of thermal conductivity (k).
