For each of the situations described below, the object considered is undergoing some changes. Among the possible changes you should consider ar (0) The object is absorbing or giving off heat (T) The object's temperature is changing (E) The objects thermal energy is changing . (W) The object is doing mechanical work or having work done on t (C) The objects chemical energy is changing For each of the situations described below, identify which of the four changes are taking place and mark as many of the letters QTE WC (or none) as are appropriate 1. A cylinder with a piston on top contains a compressed gas and is sitting on a thermal reservoir (a large iron block that maintains a constant temperature) After everything has come to thermal equilibrium, the piston is moved upward somewhat (very slowly). The object to be considered is the gas is the cylinder QOT BE Qw Oc 2. Consider the same cylinder as in part 1, but it is wrapped in styrofoam, a very good thermal insulator instead of sitting on a heat reserver. The po ispratie dard (aga very slowly), compressing the gas. The object to be considered is the gas in the cylinder CT CV w k 3. A mixture of two moles of hydrogen gas and one male of oxygen gas in a thermally insulated vessel of ad volume is subjected towarking nehybner) and converts to water vapor 12or De D sxx
