As the states of matter change from solid to liquid to gas, respectively, their composition changes as well. For example, in a solid, the bonds are stronger than hydrogen bonds. That allows the solid substance to have a definite volume and shape. However, when the heat is added to the solid and it melts to become a liquid, the bonds are considerably weaker, and in water, are simply hydrogen bonds. A liquid has a definite volume but not a definite shape, and it thus takes the shape of the container in which it is. When "more" heat is added, the liquid substance evaporates and becomes a gas, which has no bonds at all. Gas is simply a formless collection of particles that tends to expand in all directions at the same time in order to occupy its full container. If a gas is not confined, the space between the particles will continue to increase. A gas has neither a definite volume nor a definite shape.
In this pattern, solid to liquid to gas, heat is being added in order to provoke the phase change. In the other "direction," gas to liquid to solid, heat is being released through the phase change.
It often helps to think of an ice cube when thinking of phase changes. An ice cube is a solid, and when heated up, it becomes liquid water. When heated up some more, it becomes water vapor, which is a gas.

Stomach cancer
Stomach cancer, or gastric cancer, is a kind of cancer from any part of the stomach. Stomach cancer causes about 800,000 deaths worldwide per year. The odds of survival are 5 to 15%. The life span of someone with stomach cancer is five to fifteen years. This is because this type of cancer can spread faster than other cancers.
Most stomach cancer is caused by "Helicobacter pylori" infection. Diet foods are not proven causes, but some foods, such as smoked foods, salted fish and meat, and pickled vegetables are associated with a higher risk.
Bembridge
"Bembridge" is a village on the Isle of Wight. It is the village which is farthest to the east on the island. According to the 2001 census of the United Kingdom it had a population of 3,848. The large population (for a village) means that some people have said that it has the biggest population of any village in the United Kingdom. Many of the most rich people who live on the Isle of Wight live in Bembridge.
The villages of Bembridge and Yaverland were once a separate island, off the coast of the rest of the Isle of Wight. There was a channel of water called Brading Haven, which separated the two islands. Before the time in which Queen Victoria was the queen of the United Kingdom, the village of Bembridge only had a few huts and farm houses. It was only when a church was built in 1827 that the village started to grow.
The most old buildings in the village are found close to the church in the north of the village. In this part of the village there are a number of shops, pubs (places to buy and drink alcohol), and restaurants (places to buy food). There is also the village hall (a place for meetings, sales and events).
In the south of the village there is an area which is called 'Lane End'. It is a more modern part of the village and has its own shops. In this part of the village there is a lifeboat station. There are two schools in Bembridge, one is for children of ages 4–8, and the other is for children of ages 9–13.
United States Secret Service
The United States Secret Service (which is often just called the Secret Service in the United States) is part of the United States government. Part of its job is to investigate when people make fake money. (Making fake money is called counterfeiting). However, the United States Secret Service is more well known for protecting important government leaders. Secret Service agents work as bodyguards and protect people like the President, Vice President, members of the United States Cabinet, people who are running for high office, and the family members of these people, and leaders from other countries who are visiting the United States. There are other people whom the Secret Service protects, too. A United States President would never be seen in public without Secret Service agents protecting him or her at all times.
It is often not easy to recognize Secret Service agents, because they often dress to blend in wherever they are. This means that they will often be dressed the same way as everybody else in a crowd.
They employ about a total of 5,000 people.
The United States Secret Service was created in 1865 to stop counterfeiters. It did not start protecting the President until after President William McKinley was shot and killed in 1901. In 1902, President Theodore Roosevelt became the first President of the United States to be protected by Secret Service agents. Since then, every president has received Secret Service Protection. In 1981 when Ronald Reagan was shot, Timothy McCarthy became one of four Secret Service agents to take a bullet of a President.
The Secret Service used to be part of the Treasury Department, but is now part of the Department of Homeland Security.
