Activity In this activity, you will open the gas properties simulation C and follow the instructions provided with each question below.
Part A
Using the controls along the right side of the simulation, under "Options," check the second box to select the temperature of the new particles.
Then move the slider at the bottom to its lowest setting (50 K). Next, choose temperature as your constant parameter at the top. In the "Gas in
Chamber" box, add "light species" particles until about 50 are in the box. Pay careful attention to how the particles move. Finally, add about 50
"heavy species" particles to the box, paying attention to how the heavier particles move. Write your observations on how particles of different
masses move.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

i'm pretty sure its b i might be wrong though!

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
