If the gas is cooled, the particles will move more slowly, because they will have less energy.  Gaby is examining a particle that slowed down after she cooled some gaseous CO2. Why did the particle slow down it has more energy or it has less energy?
it has less energy

The size of the eroded particles depends on the velocity of the water. Eventually, the water deposits the materials. As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited.  Wendy turned the hose from full blast to half power. This makes the stream more or less likely to be able to deposit large rock particles?
less

The closer the charged objects are, the stronger the electrostatic force.  Robby noticed a weak electrostatic force between two charged objects. He wanted to decrease the strength of this force. So how should he position them Closer together or Farther apart?
Farther apart

The folds present in the membrane increase the surface area allowing more ribosomes to be present on the ER, thereby allowing greater protein production.  If Mona is creating a membrane to filter out some dirty water and she creates more folds in the membrane, what happens to the total surface area of that membrane increases or decreases?
increases
