General statement Particular statement1. Water boils at 100°C. The water in the kettle is boiling. 2. Air pressure is measured with The pressure on high mountain is a barometer. lower than at ground level. 3. Temperature is measured with Last Sunday the temperature a thermometer. was +25°C. 4. Liquids are denser than gases. The liquid in this bottle is dense. 5. Oil contains sulphur. The oil in the North Sea contains little sulphur. XI. Open the brackets using the construction the … the. 1. (Чем раньше) a fire is detected, (тем легче) to put it out, and (тем меньше) the threat to the people. 2. (Чем выше) the temperature, (тем быстрее) the motion of the molecules and (тем больше) the pressure exerted on the walls of the container. 3. (Чем выше) the pressure of a gas, (тем выше) its temperature. 4. (Чем больше) a gas is compressed, (тем больше) its resistance to compression.
XII. This table represents the list of substances having an explosibility index. The indexes are arbitrary set at 1 for a dust equivalent to Standart Pittsburgh coal. The purpose of these indexes is to give a relative comparison of the hazard involved. An explosibility index of 1 to 10 is classified as a strong explosion; an index above 10 is classified as a severe explosion. Make predictions, from the Table, about the possibilities of the explosions.
Ways of expressing probabilities:
e.g.: The possibility that potato explosion will happen is extremly high.
