Does a cubic meter of natural gas mean liquid or gas?

Natural gas, one cubic meter, refers to gas or liquid?

Does a cubic meter of natural gas mean gaseous or liquid? The personal view given by the household miscellaneous altar is that the cube of natural gas refers to the gaseous state. Sometimes when we pay at home, we say that we use one cubic meter of natural gas, so this time we are talking about gaseous natural gas. Why gaseous natural gas?

The reasons are mainly based on the following three points.

①: The weather is transported in gaseous state.

That is to say, our natural gas is transported from the gas source through the pipeline, and it is transported in the pipeline in the form of gas. This is definitely different from our common canned liquefied petroleum gas, and its nature is different.

②: The weather is calculated in cubic meters.

As can be seen from this unit, the natural gas we use is gaseous. Because the natural gas consumption in our home is usually several cubic meters per month. If it is liquid natural gas, the number of cubes is very huge. According to the experimental data, the conversion of a cubic liquid into a gas may increase by about 6200 times. So it can also be seen from this point that the cubic natural gas we are talking about cannot be liquid natural gas.

(3) We also need to know another point, that is, each cubic meter of natural gas we are talking about is the corresponding volume at standard atmospheric pressure and normal temperature of 20℃.

Because the volume of natural gas changes greatly with the change of pressure. That is to say, although we are talking about one cubic meter, the amount of natural gas contained in the pipeline will be different if the pressure is different. In other words, the pressure in our common gas pipelines includes high pressure gas pipelines, medium pressure gas pipelines and low pressure gas pipelines. The difference between them is that the conveying pressure in the pipeline is different. For example, like our common medium-pressure gas pipeline, it is generally around 1000Pa to 2000Pa.

Comprehensive analysis: Through the introduction of natural gas at the above three points, we can all find that our domestic natural gas refers to a standard atmospheric pressure and normal temperature gas volume. This is also a standard for us to pay for natural gas.

How to save the use of natural gas?

For natural gas, if we use it in large quantities, the monthly cost is also very high. When we use gas at home, we should also learn some specific small measures to save the use of natural gas, so that we can also lack money every month, which is also a big expense accumulated over the years.

I personally recommend the following five common car coups.

①: Avoid burning empty stoves.

The so-called avoid burning an empty stove means that you can't turn on the gas stove when cooking, but don't put the pot. For example, we usually turn on the gas stove before the cooking materials are ready. This kind of gas stove burns there and burns the stove empty. This will waste a lot of natural gas.

②: Learn to control the size of fire.

When a gas stove is in use, it is usually fired first and then turned off. Especially when cooking at home, we first boil the rice with a big fire, and then turn to a small fire and stew it slowly. This will make the rice delicious and save natural gas.

③: Try to stew when cooking, and try to avoid steaming.

Because cooking may taste better when steamed on the fire, a lot of natural gas is wasted in this process, and the consumption of natural gas in steamed state is several times that of braised rice.

④ Wipe the pots used at home to avoid oil pollution.

Especially some cooking pots, such as those used for many years, have a thick layer of oil at the bottom, which wastes a lot of natural gas to heat the pot, which is unreasonable.

⑤: Try to use the windshield.

For the residents in the building, this generally does not exist. That is, when we use the cooker, the flame can't swing from side to side, which will make the heat not be fully utilized. Try to let the steady flame heat our pot.
