Go to phet. colorado. edu/ and search for gas properties (you want the HTML5 version) Or go to https://phet. colorado. edu/sims/html/gas-properties/latest /gas-properties_en. html Select Ideal and nothing should be constant (checkbox). Add some gas with the pump and play with the simulation and answer the following questions. In each case, be very specific about the variables and the molecules and be sure to talk about why the changes are happening considering KMT. a. What happens if the sample’s temperature changes? b. When would we consider it a real gas and what would be different (the simulation doesn’t show it)? c. What happens if you change the volume? d. What happens if you change the pressure? e. When would we consider it a real gas and what would be different (the simulation doesn’t show it)? f. What happens if you change the amount of gas? g. What happens if you change or mix the type of gas?

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
