YÖKDİL Fen Cloze Test Soruları

Question 1

Superconductors are materials that conduct electricity with no resistance at all (1)---- they are cooled below a certain critical temperature. In an ordinary wire, some electrical energy is always lost as heat, but in a superconductor a current can flow without any loss. Superconductors also (2)---- magnetic fields from their interior, which allows a magnet to float above them. These properties have made them essential in devices such as the powerful magnets used in medical imaging machines. The main obstacle to wider use is that most superconductors (3)---- operate only at extremely low temperatures, which requires expensive cooling with liquid helium. The discovery in the 1980s of materials that become superconducting at higher temperatures (4)---- great excitement, since some of them can be cooled with liquid nitrogen, which is far cheaper. Nevertheless, these materials are often brittle and difficult to shape into wires, and scientists are still searching (5)---- a superconductor that works at room temperature.

Question 6

Lightning is a giant electrical discharge that occurs when charges build up within storm clouds. Inside a thundercloud, strong upward currents of air carry water droplets and ice particles to great heights, (1)---- they collide with one another. These collisions transfer electrical charge, so that the upper part of the cloud usually becomes positively charged (2)---- the lower part becomes negatively charged. When the difference in charge grows large enough, the air, which normally acts (3)---- an insulator, can no longer prevent the flow of electricity, and a lightning flash occurs. The discharge heats the surrounding air to extremely high temperatures within a fraction of a second. This sudden heating causes the air to expand explosively, (4)---- produces the sound we hear as thunder. Because light travels much faster than sound, observers see the flash before they hear the thunder, and the delay between the two can be used to (5)---- how far away the storm is.

Question 16

A tsunami is a series of ocean waves caused by the sudden displacement of a large volume of water. Most tsunamis are (1)---- by undersea earthquakes that occur when one tectonic plate suddenly slips beneath another, lifting or dropping the seabed. Landslides and volcanic eruptions can also generate tsunamis, (2)---- these are less common. In the open ocean, tsunami waves may be less than a metre high and can pass beneath ships almost unnoticed. They travel at very high speeds, (3)----, especially over the deepest parts of the ocean. As the waves approach the coast and the water becomes shallower, they slow down and their energy is concentrated into a smaller volume of water, causing them to grow dramatically (4)---- height. Because the waves are so hard to notice in the open ocean, warning systems combine seismic data with measurements from ocean sensors that can detect small changes in sea level (5)---- the waves reach the shore.
