Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "What are some things density explains?"

Answer: "It explains why helium balloons rise"

One day, Phoebe woke up and found that her house had been broken into. Her front door was wide open. She went into the living room and saw that her television set and stereo were missing. She checked the kitchen, but didn't find anything missing there except for a clock. Then she saw that her purse had been stolen too. She called the police to report what had happened. The police officer told her that there had been a lot of cases like this in her neighborhood lately, and they were looking for the criminals. Phoebe went into her bedroom and started to cry. She had no money to buy a new television set or stereo. She was scared that the robbers might try to break into her house again. She called her friend Mary and asked her what to do. Mary told Phoebe to change her front door lock right away. She said she knew a detective who could try to find the robber who had broken into her house. Phoebe thanked Mary, and said she felt safe knowing that there was someone who could help her catch the robber so he wouldn't do it again.

If you beat a dog in Schuylkill County, you'll probably get a $100 fine. If you repeatedly beat a woman, you'll probably get the same fine. In 2001, county judges heard 98 Protection From Abuse cases, finding the defendant guilty in 48 percent of those cases, either after a hearing or through a technical violation or plea. Of those found guilty, the majority were ordered to pay court costs, plus a $100 fine. No defendants were ordered to pay more than a $250 fine for violating the court order. In 27 percent of the cases, the charges were dismissed or the defendant was found not guilty. In the rest of the cases, charges were withdrawn or the matter is not yet resolved. Sarah T. Casey, executive director of Schuylkill Women in Crisis, finds it disturbing that in most cases, the fine for violating a PFA is little more than the fine someone would get for cruelty and abuse toward an animal. "In most of the counties surrounding Schuylkill County, the penalties given for indirect criminal contempt are much stiffer than those in Schuylkill County," Casey said. "What kind of message are we sending those who repeatedly violate Protection From Abuse orders? That it's OK to abuse women in Schuylkill County, because you'll only get a slap on the wrist?" Under state law, the minimum fine for contempt of a PFA is $100; the maximum fine is $1,000 and up to six months in jail. Like others who are familiar with how the county's legal system does and doesn't work for victims of domestic violence, Casey believes some changes are in order. Valerie West, a manager/attorney with Mid-Penn Legal Services, with offices in Pottsville and Reading, regularly handles domestic violence cases. She finds fault with the local requirement that a custody order must be established within 30 days after a PFA is filed. West said she feels a custody order should be allowed to stand for the full term of the PFA - up to 18 months - as it does in many other counties in the state. "It places an undue burden on the plaintiff, in terms of cost, finding legal representation and facing their abuser - not to mention a further burden on the system to provide those services," West said. "It may be difficult for the parties to reach an agreement so soon after violence has occurred.

Question: "If you beat a dog and woman in Schuylkill County how much of a fine will you need to pay?"

Energy is stored in chemical compounds. This energy is called chemical energy. Chemical energy is a form of potential energy. When bonds between atoms are broken, energy is released. The wood in fireplaces has chemical energy. The energy is released as heat and light when the wood burns. Most living things get their energy from food. When food molecules are broken down, the energy is released. It may then be used to do work, like playing ball or studying science. If you have ever heard, "Eat a good breakfast", thats why. You need energy to do things during the day. To do those things you need energy. You get your energy from the food you eat. That energy is stored in your body until you need it. How did you get to school today? If you walked, you used chemical energy from the food you ate. What if you rode the bus or were driven in a car? Where did that energy come from?

Question: "Does wood have potential energy?"

Answer: "Sometimes"

Response:
no
