Physical properties include the state of matter. We know these states as solid, liquid, or gas. Properties can also include color and odor. For example, oxygen is a gas. It is a major part of the air we breathe. It is colorless and odorless. Chlorine is also a gas. In contrast to oxygen, chlorine is greenish in color. It has a strong, sharp odor. Have you ever smelled cleaning products used around your home? If so, you have probably smelled chlorine. Another place you might smell chlorine is at a public swimming pool. The chlorine is used to kill bacteria that may grow in the water. Other physical properties include hardness, freezing, and boiling points. Some substances have the ability to dissolve in other substances. Some substances cannot be dissolved. For example, salt easily dissolves in water. Oil does not dissolve in water.

Name a sunstance that is odorless in all physical forms.

Washington (CNN) -- The Pacific island nation of Palau has agreed to take in 17 Chinese Muslims held at the U.S. prison camp at Guantanamo Bay, Cuba, the country's ambassador to the United States said Wednesday. The map shows the Pacific island nation of Palau in relation to China. Details of the transfer are still being worked out, Ambassador Hersey Kyota told CNN. But Kyota said his country, a former U.S. Pacific trust territory, has agreed to take in the ethnic Uighur detainees "for humanitarian reasons" and because of the "special relationship" between Palau and the United States. U.S. State Department spokesman Ian Kelly would not comment on the announcement, telling reporters, "We're still involved in ongoing discussions." The agreement includes some U.S. aid for Palau, Kyota said, but he said those details remained to be worked out as well. The country, with a population of about 20,000, is about 1,000 miles southeast of Manila, Philippines, and about 4,600 miles west of Hawaii. Palau has received nearly $900 million in U.S. aid since independence in 1994, according to congressional auditors, and depends on Washington for defense. The "Compact of Free Association" between Palau and the United States is up for review, but Kelly said any additional aid offer "is not linked to any other discussions we may be having with the government of Palau." The Uighurs were accused of receiving weapons and military training in Afghanistan.

So it was that J.W. and Marty had come into the inner places of each other's lives. Of all the developments of Institute week, naturally the one which filled J.W.'s thoughts with a sort of awed gladness was Marty's decision to offer himself for the ministry. Joe Carbrook's right-about-face was much more dramatic, for J.W. saw, when the decision was made, that Marty could not have been meant for anything but a preacher. It was as fit as you please. As to Joe, previous opinion had been pretty equally divided; one side leaning to the idea that he might make a lawyer, and the other predicting that he was more likely to be a perpetual and profitable client for some other lawyer. In the light of the Institute happenings, it was to be expected that the question of college would promptly become a practical matter to four Delafield people. Marty was greatly troubled, for he knew if he was to be a preacher, he must go to college, and he couldn't see how. J.W. felt no great urge, though it had always been understood that he would go. Marcia Dayne had one year of normal school to her credit, and would take another next year, perhaps; but this year she must teach.
What would Marty have to do to become a preacher?
