If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

Question: "What can cause wood to change to ashes, carbon dioxide, water vapor, and other gases?"

Answer: "Fire"

Response: yes

Renewable Energy Resource Sunlight Sunlight can be used to heat homes. It can also be used to produce electricity. This conversion is made possible by solar cells. However, solar energy may not always be practical. Some areas are just too cloudy. Example Solar panels on the roof of this house generate enough electricity to supply a familys needs. Moving Water Falling water can have a lot of energy. Its energy can be converted into kinetic energy. This energy can turn a turbine and generate electricity. The water may fall naturally over a waterfall or flow through a dam. A drawback of dams is that they flood land upstream. They can also reduce water flow downstream. Either effect may harm ecosystems. Wind Wind is moving air. It has kinetic energy that can do work. Wind turbines change the kinetic energy of the wind to electrical energy. Only certain areas of the world get enough steady wind. Many people also think that wind turbines are noisy and not very nice to look at.

Question: "What are the sources of kinetic energy"

Answer: "Moving water and wind"

Response: yes

Life for the partners of Cates, Katalinic & Lund holds little of the glamour one might expect from a career in law. Instead of lunches at Lutce, they caucus at the Palace Diner in Queens. Wooing clients means passing out fliers on street corners, not securing box seats at Madison Square Garden. To make ends meet, one partner stacks pipe and cleans the yard at a plumbing warehouse. Another handles urine samples in a hospital lab. A sign of failure, of a feeble economy, perhaps? Hardly. They are heeding the call of a growing pool of law schools, which are for the first time pointing graduates in a new direction and teaching them how to get there. Forget the lure of large firms, the security of a government post. Here is how to grapple "in the service of justice," as many of the schools put it, instead. Convinced that corporate largess and government programs barely dent the nation's legal needs, the law schools are urging graduates to buck tradition, pass up big salaries and ignore mushrooming student debt to join tiny neighborhood practices or simply start their own, all with an eye toward charging no more than their clients can afford. This is not pro bono legal work; it is "low bono," a term the schools coined to define the atypical kind of law career they are training students for. While its practitioners do charge for their services, they are also dead set on turning no one away - or at least as few as possible. "When you go into this kind of social justice law, it's really brutal and you're almost guaranteed to struggle for a couple of years before there's a light at the end of the tunnel," said Fred Rooney, director of the Community Legal Resource Network at City University of New York School of Law, from which the lawyers of the newly formed Cates, Katalinic & Lund graduated last May. "But if our graduates don't do it, the millions of people who cannot access justice in this country will continue to soar." The movement, primly called the consortium, started four years ago by CUNY, Northeastern University, the University of Maryland and St. Mary's Law School in Texas. (St. Mary's later dropped out.) Since then, it has drawn seven additional law schools to its ranks: the University of Michigan, Rutgers and Syracuse Law Schools, New York Law School, University of New Mexico School of Law, Thomas M. Cooley Law School and Touro Law School. It has elicited at least initial interest from 19 more.

Question: "Consdider the original schools in the consortium and those that have joined to find out how many are currently teaching this type of law."

Answer: "Rutgers and Syracuse Law Schools"

Response: yes

Powell contended that it was not inconsistent to want to foster cooperation even with an organization like the Indonesian military, which has a history of human rights abuses. "If you get young officers, expose them to a military organization that is within a democratic political institution, such as the United States, then that rubs off on them," he said. In Malaysia, Powell met with Prime Minister Mahathir Mohamad, who has led the country since 1981. The Malaysian foreign minister, Syed Hamid Albar, later told local reporters that Powell had proposed that American and Malaysian officials review the idea of forming a regional training center in Malaysia to coordinate antiterrorism activities. His brief stop in Malaysia also highlighted the moral ambiguities of the effort to prevent terrorism and its emphasis on cooperation with governments that the United States has often criticized. The United States once distanced itself from Mahathir for strong-arm tactics with political rivals, and human rights groups criticize him for arresting and jailing scores of suspected militants, including some who may be linked to al-Qaida, without trial. Powell said his discussions with Mahathir "touched on the case" of his former deputy, Anwar Ibrahim, who is serving a 15-year sentence on charges of sodomy and abuse of power after trials that Powell said the United States had "always felt" were flawed. The assistant secretary of state for East Asian and Pacific affairs, James Kelly, met on Tuesday morning with Anwar's wife, Wan Azizah Wan Ismail, for what she later told Malaysian reporters was a discussion about both the detention of her husband and six supporters, and the campaign against terrorism.

Question: "What was the purpose of Powell's trip to Malaysia?"

Answer: "To explore cooperative anti-terrorism efforts between the US and Malaysia by meeting with the Prime Minister, including the idea of creating a regional training center in Malaysia"

Response:
yes
