Exercise 18. Read the text B without a dictionary for 4 min.
Text B
PETROLEUM
Colour, odour, specific gravity, and viscosity are the main physical properties of petroleum. Another important determination made in connection with petroleum products is that of the flash and burning points. The flash point may be defined as the temperature at which the vapours arising from the heated oil will ignite with a flash of very short duration, when a small flame is passed over the surface. This is of the utmost importance, as it indicates the temperature at which oil will ignite. The specific heat of the hydrocarbons in each series decreases with increase in molecular weight. The heat of vaporization decreases with increase in molecular weight.
Crude oils differ markedly in their boiling points and the amount of distillate which is obtainable at definite temperatures. The boiling point of the crude oil will depend largely on the hydrocarbons. A petroleum of low specific gravity will usually contain a larger proportion of the more volatile hydrocarbons, whereas in a crude of high specific gravity, high boiling hydrocarbons generally predominate.
Exercise 19. Answer the following questions .
What are the main properties of petroleum?
How may the flash point be defined?
Why does temperature decrease?
What does the heat vaporisation depend on?
What will the boiling point of the crude oil depend on?
What will a petroleum of low specific gravity contain?
Where do high boiling hydrocarbons generally predominate?
Exercise 20. Agree or disagree with the following sentences .
Colour, odour, specific gravity and viscosity are the main chemical properties of petroleum.
The flash and burning points are also the main physical properties of petroleum.
The specific heat of hydrocarbons in each reduce with increase in molecular weight.
The heat of vaporization decreases with increase in molecular weight.
Crude oils differ markedly in their melting points.
The boiling point of the crude oil will depend largely on the hydrocarbons.
A petroleum of low specific gravity will usually contain a larger proportion of the less volatile hydrocarbons.
In a crude of high specific gravity high boiling hydrocarbons generally predominate.
Exercise 21. Speak about the main physical properties of petroleum.
VI. Reading and сomprehension. Exercise 22. Read the text c without a dictionary for 4 min. And answer the following questions in your native language.
1.What origin has petroleum?
2.What is the difference in the formation of coal and petroleum ?
3.What geological formation is favourable for oil drilling ?
4.What can you say about natural supplies of coal and petroleum ?
