Abstract

A thermally insulated vessel fitted with a large valve contains air at \(\, 50\,^{\circ }\mathrm{C}\) and \(\, 0.5~\mathrm{bar}\). The valve is opened so that additional air from the surrounding atmosphere at \(\, 0\,^{\circ }\mathrm{C}\) and \(\, 1~\mathrm{bar}\) enters the vessel. What is the temperature of air in the vessel after it comes to rest but before it exchanges any heat with the walls?
