Albert places a thermometer in hot water during a lab and the column of fluid inside the thermometer rises to 90 degrees Celsius. As the student takes measurements of the temperature, it drops until it reaches 24 degrees Celsius, room temperature. When the data is graphed, Albert notices that the initial decrease in temperature is more rapid. How should he explain his observation?

The pressure inside a hydrogen-filled container was 2.10 atm at 21 ? c. what would the pressure be if the container was heated to 92 ? c ?

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.
