Question

Сравните свойства нефти с природным газом

Answer 1

Нефть и газ происходят из недр земной коры ( в этом они схожи)

Св-ва : Нефть - горючие полужидкое вещество тёмного цвета.

Природный газ- газ со специфическим запахом , не имеет цвета , легко воспламеним.

Применяются и сера и газ для заправки авто , для обогревания и т.д.

Способы добычи : нефть специальными установками выкачивают из земных пород ( и даже со дна морей и океанов). Газ выкачивают из недр Земли.

Транпортируют их одинаково : по трубопроводам , железнодорожными путями в цистернах и на специальных бензовозах , и танкерах (коробли перевозящие нефть и газ).

Answer 2

Привет! Как дела! У меня норм

Answer 3

Properties of Oil:

- Composition: Oil is a complex mixture of hydrocarbons, which are organic compounds made up of hydrogen and carbon atoms. The composition of oil can vary depending on its source, but it typically contains a mixture of different hydrocarbon molecules. - Density: Oil has a lower density compared to water, which is why it floats on the surface of water. The density of oil can vary depending on its type and composition. - Viscosity: Oil has a higher viscosity compared to water, meaning it is thicker and flows more slowly. The viscosity of oil can vary depending on its temperature and composition. - Flammability: Oil is highly flammable and can easily catch fire. This is due to the presence of hydrocarbons, which are combustible substances. - Energy Content: Oil is a rich source of energy and is commonly used as a fuel for various purposes, including transportation, heating, and electricity generation. The energy content of oil is measured in terms of its calorific value, which is the amount of heat released when it is burned.

Properties of Natural Gas:

- Composition: Natural gas primarily consists of methane (CH4), but it can also contain small amounts of other hydrocarbons such as ethane, propane, and butane. The exact composition of natural gas can vary depending on its source. - Density: Natural gas has a lower density compared to air, which is why it tends to rise and disperse in the atmosphere. The density of natural gas is lighter than that of oil. - Flammability: Natural gas is highly flammable and can easily ignite when exposed to a spark or flame. It is important to handle natural gas with caution to prevent accidents. - Energy Content: Natural gas is a clean-burning fossil fuel and is widely used for heating, cooking, and electricity generation. It has a high energy content and produces fewer greenhouse gas emissions compared to other fossil fuels.

In summary, both oil and natural gas are fossil fuels that are used as sources of energy. They have different compositions, densities, and energy contents. Oil is a liquid with higher viscosity and density compared to natural gas, while natural gas is primarily composed of methane and has a lower density. Both oil and natural gas are highly flammable and have significant energy content.
