We are all used to measuring liquids in specific volume units: milliliters or liters. However, sometimes it is required to know exactly the mass of one or another liquid substance. At least for transporting it, in order to know, this or that container, this or that transport with a certain carrying capacity is suitable. How to find out the mass of such a liquid substance as gasoline?
What is gas?
Gasoline is a mixture of hydrocarbons used as motor fuel and raw materials in industry for organic syntheses.
There are a lot of different types of gasoline in the modern world: it is automobile, aviation, and gasoline-solvent, and even separate gasoline for petrochemicals - naphtha.
Yes, humanity recognizes the harm of using this substance as fuel for the environment, for human health, for the planet as a whole. A study was conducted and it was even proved that with constant contact and work with gasoline, the risk of cancer increases significantly. An ordinary car owner is at risk of disease simply because he provides ongoing care or repair of his vehicle.
Therefore, there is a search for alternative fuel means, there are certain results, although gasoline is still the main motor fuel.
How much does a 25 liter gas tank weigh?
For gasoline of different brands, the weight of one liter is known. It is important to consider that the temperature at which measurements were made is 20 Ā° C, and this is important. Since there are exact patterns of change in weight and mass depending on the ambient temperature.
On average, the weight of one liter of A-76 gasoline is 0.730 kg; A-80 - 0.730 kg; A-92 - 0.760 kg; A-95 - 0.750 kg; A-98 - 0.780 kg. In order to obtain more generalized information, we will calculate the average weight of 1 liter of gasoline, knowing the arithmetic average of the data obtained: that is, on average 1 liter of gasoline weighs 0.75 kg (remember that at +20 Ā° C).
Based on this, it is easy to calculate how much gasoline weighs 25 liters - an average of 18.75 kg. Well, a pretty large number. Interestingly, it would be possible to approximately estimate the weight of gasoline without special knowledge? Probably with difficulty. To estimate the weight of a liquid substance, it is necessary to know at least approximately its density, and it is rather difficult to evaluate it only by the consistency or appearance of the liquid.
It is also easy to calculate with what force 25 liters of gasoline affect the earth, that is, how much gas weighs 25 liters in newtons. To do this, we will use such a unit of measure of force as newtons. To translate the mass in kilograms into newtons, it is enough to multiply it by the acceleration of gravity equal to 9.8 m / sĀ².
From the school physics course, we can remember that this value is the same for all objects on our planet. After making simple calculations, it turns out that 25 liters of gasoline is 183.75 N. And now just imagine the force with which all gasoline in the world acts on Earth. And this is just the fuel that people pour into their vehicles when they are traveling on business. In a word, a small part of everything existing on the planet.
