A cylinder is initially filled with saturated vapor mixture of R-134a at a specified pressure. Heat is transferred to the cylinder until the refrigerant vaporizes complately at constant pressure. The initial volume, the work done and the total heat transfer are to be determined (x1 = 0,25 m = 0,2 kg, p = 200 kPa)

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
