Consider the graph. A graph labeled Heating Curve has time as the horizontal axis and Temperature as the vertical axis. A line starts at 0 and rises to 1500 degrees where it levels off briefly; this section of line is labeled solid. The line continues to rise until it levels off at about 2750; this curve is labeled Liquid. After running horizontal for some time, the line rises again; this curve is labeled Gas. Based on the information in the graph, which statement best applies to a gas? Its particles have the highest average kinetic energy. Its particles have the smallest volume of all three states of matter. Its particles are slowing down because of a temperature increase. Its particles are moving apart due to repulsion between them.

Transportation is the largest single source of air pollution in the united states. air pollution can harm the environment and human health. which technology could offer a solution to this problem? mufflers that reduce noise motors that run on electricity tires that improve gas mileage

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.
