Following problem is based on thermodynamic law. Answer the questions given at the end of it. The second law of thermodynamics is a fundamental law of science. In this problem we consider the thermodynamics of an ideal gas, phase transition and chemical equilibrium.
Three moles of `CO_(2)` gas expands isothermally (in thermal contact with the surroundings, temperature `=15^(@)` C) against a fixed external pressure of 1.00 bar. The initial and final volumes of the gas are 10.0 L and 30.0 L, respectively.
`Deltas_("surroundings")` is
