Which forces are intramolecular and which intermolecular?
xxTIMURxx [149]

On a chilly, humid evening, intermolecular forces enable fog to form. The gaseous water molecules condense as a result of powerful molecular interactions.

What force allows fog formation?

From the south, warm, moist air is brought in, and if there is snow or cool precipitation on the ground, it will come into touch with the warm, moist breezes. The air coming in will cool as a result of this air-ground contact. Dew point rises at that position, leading to high humidity and the formation of fog.

What is molecular interactions?

Interactions between molecules or between atoms without bonds are referred to as molecular interactions. There are three types of molecular interactions: cohesive (attraction between like), adhesive (attraction between unlike), and repulsive forces.

Which is the most important factor in determining the state of a substance?
tekilochka [14]

Answer:

The balance between intermolecular forces and kinetic energy

Explanation:

If the kinetic energies of the particles are not strong enough to overcome the intermolecular forces, the particles will be locked in place in a crystal lattice. The substance will be a solid.

If the kinetic energies of the particles are slightly stronger than the intermolecular forces, the particles will be able to slide past each other. The substance will be a liquid.

If the kinetic energies of the particles are much stronger than the intermolecular forces, the particles will be escape completely from the attractions of their neighbours. The substance will be a gas.

4) In the experiment, why do you think they started with water that was the same temp (118 °F) for each
kondor19780726 [428]

Answer:

4. I think that they started with water that was the same tsmpurature because if they didnt start with the same temp of water then it would be harder to tell which one was better. and could hold the most heat.

5. yes i think it would matter, because if you have more water in one cup it might stay warmer than it would with the cups with less water, and if it was thicker it would hold mor heat because it is not so thin that the heat is just gonna come out it has to come through more for the heat to get out.

Explanation:

sorry if these are to long but thats how i would answer them.

hope it helped

During which phase change do water molecules form crystal lattice?. A.Melting. B.Freezing. C.Boiling. D.Condensing.
nadezda [96]
The phase in which water molecules form crystal lattice is : B. Freezing

When water undergone a freezing phase, it will trapped a specific amount of Gases inside it. Crystal lattice is basically the gas molecule that trapped within the water
