Reading. Text 1. ( From The Worst-Case Scenario Handbook )

How to Survive in Frigid Water 1) Do not attempt to swim unless it is for a very short distance. A strong swimmer has a 50-50 chance 0f surviving in 50-degree Fahrenheit water. Swim only if you can reach land, a boat, or a floating object with a few strokes. ( Swimming moves cold water over skin, causing rapid cooling. Cold water saps body heat 25 times faster than air of the same temperature, and water any colder than 70 degrees Fahrenheit can cause hypothermia ). 2) If you are alone and wearing a personal flotation device (PFD), assume the Heat Escape Lessening Posture (HELP). Cross your ankles, draw your knees to your chest, and cross your arms over your chest. Your hands should be kept high on your chest or neck to keep them warm. Do not remove clothing. Clothes will not weigh you down but will hold warm water against your skin like a diver’s wetsuit. This position can reduce heat loss by 50 percent. 3) If two or more people are in the water and all are wearing personal flotation devices (PFDs), assume the “huddle” position. Two or four people should “hug”, with chest touching chest. Smaller individuals can be sandwiched between larger members. This position allows body heat to be shared. Also, rescuers can spot groups more easily than individuals.

State true or false sentences:

1. An average person swimming 50 yards in 50-degree water has a 50 percent chance of surviving.

2. Air lowers body heat 25 times faster than water of the same temperature.

3. Generally, when stranded in frigid water, you should try to swim to the closest floating object.

4. When alone and wearing a PFD in cold water, you should wrap your arms around your stomach.

5. In this article, HELP stands for heat escape lessening posture.

6. Always remove clothing when stranded in water, because it will weigh you down.

7. The HELP reduces the body’s heat loss by 50 percent.

8. When two to four people stranded in water they should hold each other with their chests touching.

9. Smaller people stranded in the water should be held on the backs of the larger people.

10. It is more difficult for people stranded at sea to be seen by rescuers if they are in groups.

Юный экспериментатор исследовал зависимость плотности соляного раствора от времени его приготовления. Для этого он постепенно добавлял соль в колбу с 2,0 литрами воды, постоянно помешивая раствор до полного растворения соли. Раз в минуту экспериментатор снимал показания ареометра (прибора для измерения плотности жидкости). С помощью полученного по результатам эксперимента графика, определите, какую массу соли удалось растворить экспериментатору в интервале времени между 2-й и 8-й минутами
