The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and fills it to the level of a free surface. A gas forms no free surface but tends to diffuse throughout the space available; it must therefore be kept in a closed container or held by a gravitation field, as in the case of a planet's atmosphere. The distinction was a prominent feature of early theories describing the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be "dissolved" in a vapor without losing its identity, and another theory held that the two phases are made up of different kinds of molecules: liquidons and gasons. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in common. They are both forms of matter that have no permanent structure, and they both flow readily. They are fluids.
The fundamental similarity of liquids gases becomes clearly apparent when the temperature and pressure are raised somewhat. Suppose a closed container partially filled with a liquid is heated. The liquid expands, or in other words becomes less dense; some of it evaporates. In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. The combination of temperature and pressure at which the densities become equal is called the critical point. Above the critical point the liquid and the gas can no longer be distinguished; there is a single, undifferentiated fluid phase of uniform density.
Which of the following would be the most appropriate title for the passage?
A.New Containers for Fluids
B.High Temperature Zones on the Earth
C.The Beginnings of Modem Physics
D.The Properties of Gases and Liquids

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 20 to 27.
HOW WILL LIFE IN 2050 BE LIKE?
What picture do you have of the future? Will life in the future be better, worse or the same as now? What do you hope about the future?
Futurologists predict that life will probably be very different in 2050 in all the fields of activity, from entertainment to technology. First of all, it seems that TV channels will have disappeared by 2050. Instead, people will choose a program from a ‘menu’ and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers and books will come to us by computer.
In what concerns the environment, water will have become one of our most serious problems. In many places, agriculture is changing and farmers are growing fruit and vegetables to export. This uses a lot of water. Demand for water will increase ten times between now and 2050 and there could be serious shortages. Some futurologists predict that water could be the cause of war if we don't act now.
In transport, cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed of the cars and there won't be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. On the other hand, space planes will take people halfway around the world in two hours. Nowadays, the United States Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just two hours.
In the domain of technology, robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots - they do not ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere - in factories, schools, offices, hospitals, shops and homes.
Last but not least, medicine technology will have conquered many diseases. Today, there are electronic devices that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people see again and hear again. Scientists have discovered how to control genes. They have already produced clones of animals. By 2050, scientists will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have.
