What is the change of pressure, mass and density of saturated water vapor after volume compression at constant temperature? Why? Please explain the reasons for confirmation

What is the change of pressure, mass and density of saturated water vapor after volume compression at constant temperature? Why? Please explain the reasons for confirmation

After volume compression, due to the constant temperature, the saturated vapor pressure of water is constant, so a part of water vapor will become liquid water, so the total mass of gas will decline;
Although water vapor will be reduced due to compression, other gases will not be reduced (will not become liquid), so the total pressure of gas will increase;
Similarly, the density will increase

Relationship between air density and pressure in closed container with constant temperature

According to PV = NRT, bring in n = m / m, ρ = m / V, get P = ρ RT / m, where p is the pressure, V is the volume of closed container, ρ is the density, M is the average molar mass of air, is a constant, R is a constant, t is the temperature. Therefore, RT / M is a fixed value, so the density is proportional to the pressure

How to calculate the air density? Know the temperature, pressure and wind speed

PV = NRT (Clapeyron equation)

What is the density of No.0 national standard diesel at 34 ℃?

0 # diesel oil only specifies the density at 20 ℃. There is no standard for other temperatures, but it should be higher than 20 ℃. The volume of diesel oil with the same mass becomes smaller, so the density becomes larger

0 × diesel density

What's the difference between winter and summer? How much is it in summer? What's the price of one ton?

The density of No.0 diesel oil is between 0.8400-0.8600 g / cm 3 at the standard temperature of 20 ° C. Therefore, one liter of diesel oil is only equivalent to 0.84-0.86 kg of water!

The density of No.0 Yueguo 3 diesel oil is 832.1kg/m3. How many liters of diesel oil is 1 ton?

This is to know the mass and density and find the volume
V = m / ρ = 1000kg / (832.1kg / M & sup3;) = 1.202m & sup3; = 1202l [approximate value]
Mass and volume are not comparable

What is the classification of gasoline, diesel and kerosene?

The production methods of petroleum products mainly include atmospheric and vacuum distillation, catalytic cracking, hydrocracking, catalytic reforming, etc. Generally speaking, no matter what kind of processing technology, the light components in crude oil are separated first, such as LPG and gasoline, then the intermediate components, such as kerosene and diesel, and then the heavy components, such as fuel

Kerosene, diesel, gasoline?
How many tons are 1000 liters each?

The density is measured first and then calculated
Kerosene: about 0.80 tons,
Diesel: about 0.85 tons,
Gasoline: about 0.75 tons

What are the similarities and differences among gasoline, kerosene and diesel?
I hope you can list all kinds of ingredients
Do they all contain unsaturated bonds?

The carbon chains from C7H16 to c11h24 are mixed together and can be used as gasoline. The evaporation temperature of all these carbon chains is lower than the boiling point of water. That's why gasoline evaporates quickly when we sprinkle it on the ground
Kerosene is in the range of C12 to C15, followed by diesel fuel [oil is a light petroleum product, a complex mixture of hydrocarbons (about 10-22 carbon atoms). It is diesel engine fuel. It is mainly composed of diesel fractions from crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and other processes] and heavier fuel oil (such as heating oil for house heating)
[supplement: in addition, petroleum includes all kinds of hydrocarbons, saturated and unsaturated. Gasoline, diesel oil, kerosene and so on are products extracted from petroleum according to the length of hydrocarbon molecules, and they all contain unsaturated bonds!]

What about the combustion of gasoline, diesel and kerosene?

Phenomenon: from gasoline to kerosene, the flame color is light yellow (nearly colorless), light yellow, orange yellow, and the black smoke is also increased in turn, especially kerosene
Reason: all three are fractions of petroleum at different temperatures. From gasoline to kerosene, the components are heavier and heavier, and it is more and more difficult to fully burn. Therefore, the above phenomenon appears
