Electrical Bonding and Kinetic Energy Quick Check
2. Which statement describes the effect of adding more energy to a system, assuming a phase change does not occur?(1 point)
A. The particles within the system will have greater motion, and the temperature will decrease.
B. The particles within the system will have less motion, and the temperature will increase.
C. The particles within the system will have less motion, and the temperature will decrease.
D. The particles within the system will have greater motion, and the temperature will increase
3. Which statement correctly describes how attractions that hold particles break?(1 point)
A. Attractions occur due to gravitational forces. When particles have low enough energy, these forces can no longer keep particles together.
B. Attractions occur due to electrostatic forces. When particles have low enough energy, these forces can no longer keep particles together.
C. Attractions occur due to electrostatic forces. When particles move fast enough, these forces can no longer keep particles together.
D. Attractions occur due to gravitational forces. When particles move fast enough, these forces can no longer keep particles together.
4. Which statement explains why a rubber band analogy is not a perfect comparison for bonds in a substance when considering phase changes?(1 point)
A. For a phase change from solid to liquid, the bonds break completely and particles can move independently of each other.
B. For a phase change from solid to liquid, the bonds do not break completely and particles can still slide past each other.
C. For a phase change from liquid to gas, the bonds do not break completely and particles can still slide past each other.
D. For a phase change from liquid to gas, the bonds break completely and particles can move independently of each other.
5. The boiling point of benzene is 80ÂșC. Which pair of samples will have the same average kinetic energy as benzene molecules?(1 point)
A. a sample of liquid benzene at 70ÂșC and a sample of gaseous benzene at 90ÂșC
B. two samples of liquid benzene, one at 70ÂșC and the other at 80ÂșC
C. two samples of gaseous benzene, one at 80ÂșC and the other at 90ÂșC
D. a sample of liquid benzene at 80ÂșC and a sample of gaseous benzene at 80ÂșC

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 âifâ a certain set of circumstances are present âthenâ 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.
