One characteristic property of a gas is its compressibility, that is, its ability to be squeezed into a smaller volume by the application of pressure. By comparison, liquids and solids are relatively incompressible. The compressibility of gases was first studied quantitatively by Robert
Boyle in 1661. When he poured mercury into the open end of a J-shaped tube, the volume of the enclosed gas decreased. Each addition of mercury increased the pressure on the gas, decreasing its volume. ----

average distance between them.
B) While studying the composition of air, John Dalton concluded in 1801 that each gas in a
mixture of unreactive gases acts as though it were the only gas in the mixture.
C) According to Newton, the pressure of a gas was due to the mutual repulsions of the gas particles,
that is, gas molecules.

gases move faster at higher temperatures.

Smallpox (also known by the Latin names Variola or Variola vera) was a highly contagious viral disease unique to humans. It is caused by two virus variants called Variola major and Variola minor. V. major is the more deadly form, with a typical mortality of 20–40 percent of those infected. The other type, V. minor, only kills 1% of its victims. Many survivors are left blind in one or both eyes from corneal ulcerations, and persistent skin scarring—pockmarks—is nearly universal. Smallpox was responsible for an estimated 300–500 million deaths in the 20th century. As recently as 1967, the World Health Organization (WHO) estimated that 15 million people contracted the disease and that two million died in that year. After successful vaccination campaigns, in 1979 the WHO certified the eradication of smallpox, though cultures of the virus are kept by the Centers for Disease Control and Prevention (CDC) in the United States and at the Institute of Virus Preparations in Siberia, Russia.

Recent changes in American society have resulted in increasing number of minority students enrolling in colleges and universities. Differing views among these ethnic groups can sometimes cause conflicts for students of all races. Some argue that students and universities benefit from these ethnic conflicts. Same time others believe that increasing racial diversity in American colleges and university has led to a decrease in the quality of education. People who support multiculturalism in universities believe that “students who can resolve conflict in racially diverse universities will be better prepared to succeed than students at universities that are more homogeneous”. Conflict is expected, perhaps even healthy, in a social situation where people have different interests and compete for scarce resources. Some American schools are racially integrated, so “it is not surprising that students experience shock and tension when they arrive at their first experience of multiculturalism”. But shocks like this maybe a good preparation for future life. According to Duster, nowadays students are far more competent, far more eligible, far more prepared than his time.
