-Freezing

If Possible i also need examples of the following
-Londen Dispersion Forces
-Ion-Dipole Forces
-Hydrogen Bonding
-Dipole-Dipole Forces

only the bottom stufff

Answer 1

Sublimation: Mothballs made of naphthalene or p-dichlorobenzene pass directly from solid to vapor at room temperature and gas moths. Also dry ice sublimes from solid to gas.

Condensation: You come out of your house in the morning and discover that your car windshield is covered with water droplets

Melting: You butter your hot toast and...

Vaporization: You put a kettle of water on the stove, turn the gas on high, and...

Deposition: You look at some object in your kitchen that has stood around for awhile, and you find that there is a deposit of dirt and oil on it. The vaporized cooking oils and the dust have condensed.

Freezing: This winter, you get an inch of snow that ends in a freezing rain. In the morning, an arctic air mass comes through freezing the water on your sidewalks and driveway. It lasts several weeks. You come to understand the meaning of freezing.

London dispersion forces (Also called Heitler-London forces)(Named after chemical physicist Fritz London, who formulated the theory): How can helium, atomic weight just 4, ever liquefy, let alone freeze? There are no ions, dipoles, or even van der Waals forces.

Suppose that the two electrons of helium were to surge to one side of the atom for a zillionth of a second. That would produce a negative charge on that side of the atom. By default, that would leave the other side of the atom positively charged. The He atom next to the bunched up electrons would have its own electrons repelled by the unlike charge. A third He atom on the opposite side would have its electrons attracted by the "like" "positive" charge. In that zillionth of a second, all the He atoms in the sample would be converted to dipoles, all the dipoles would attract one another, and given enough pressure and low enough temperature, even He would liquefy and solidify.

Hydrogen bonding: Water boils at 100C, even though it has a molecular weight of only 18. Neon has an atomic weight of 20, and it boils waaaaaaaaaaaay below 0C. Water molecules, H-O-H, and actually shaped like boomerangs, H^H. The slightly positively charged H's are attracted to the negatively charged O's. The mutual attraction of all the H's for all the O's causes water to be a highly "associated" liquid. Hence the high boiling point.

Answer 2

Certainly we are to be witnesses of Jesus. Why Acts Chapter 1 makes that plain. Some people wonder if Jesus himself was a witness. Yes, he was! Revelation 3:14 reports that he is "the faithful and true witness." About what did he witness? According to Luke 8:1 and Luke 9:1-2,he witnessed about the good news of the kingdom. Why witnesses even imitate the pattern of going forth two by two just like Jesus sent out his disciples at Luke 10:1. How important did Jesus feel this work to be? At Luke 4:42, he plainly told those who wished him to stay that he had to leave because "Also to other cities I must declare the good news of the kingdom of God, because for this I was sent forth.” How long was this work to take place? According to Christ at Matthew 24:14: "This good news of the kingdom would be preached until the end." How serious did the disciples take the work? Well, at Acts 5:42, we are told that "Every day in the temple and from house to house they continued without letup teaching and declaring the good news about the Christ, Jesus.” Which is interesting considering the fact that the authorities thought them pests and insisted that they stop! Their reply? We must obey God rather than man. And I will bet that everyday stuff in the verse above made people feel as if it was being stuffed down their throats. But the disciples kept on. And Paul too took it seriously. At Acts 20:20 he said: "I did not hold back from telling you any of the things that were profitable nor from teaching you publicly and from house to house.” And this house to house was literally "according to houses." Greek, kai katoikous. Here kata is used with the accusative plural, in the distributive sense. Of course, Jehovah's Witnesses do not imitate every little thing. For instance, the men do not wear robes even though Jesus and the apostles did. And the men carry Bibles even though Jesus and the apostles did not. Jesus and the disciples walked or boated everywhere they went, but Jehovah's Witnesses generally use cars to get to their destinations. Although sometimes we do have to walk through jungles or even take boats! Yes, Jehovah's Witnesses really follow Jesus’ example in the ministry. Hannah J Paul
