A fire piston is a way to start fires without a match. If a fire piston compresses air from 1 atmosphere to 3 atmospheres of pressure and the air behaves ideally. How hot will the air get if it begins at 27 degrees Celsius? Answer in Celsius to the nearest degree. (Hint - Kelvin temperatures are 273.15 degrees more than the same temperature in Celsius)

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.
