How much heat does 1 kg of oxygen produce?

Oxygen is a combustible gas that reacts with combustibles (hydrogen, methane, alcohol, etc.), and the same mass of oxygen reacts with different combustibles to produce different amounts of heat. Related Links-Combustibles: Substances that can react with oxygen or other oxidants in the air are called combustibles.

Combustibles are divided into three categories according to their physical state: gaseous combustibles, liquid combustibles and solid combustibles. Most of the combustible substances are compounds containing carbon and hydrogen, some metals such as magnesium, aluminum, calcium, etc. can also be burned under certain conditions, and many substances such as hydrazine, ozone, etc., can release light and heat through their own decomposition at high temperatures.

Combustion can be divided into complete combustion and incomplete combustion. (e.g., C+O2===CO2 is completely combustion; 2c+02===2co is incomplete combustion).

There are many types of combustibles, and the list goes on. According to different chemical structures, combustibles can be divided into two categories: inorganic combustibles and organic combustibles. The inorganic elements in inorganic combustibles are:

potassium, sodium, calcium, magnesium, phosphorus, sulfur, silicon, hydrogen, etc.; Inorganic compounds include: carbon monoxide, ammonia, hydrogen sulfide, phosphine, carbon disulfide, hydrazine, hydrocyanic acid, etc. Organic combustibles can be divided into low molecular weight and high molecular weight, and can be divided into natural and synthetic.

In addition to polyhalogenated hydrocarbons such as carbon tetrachloride, difluoro-chloro-bromomethane (1211) and other non-flammable and can be used as fire extinguishing agents, most of the other organic compounds are combustible. Organic combustibles include: natural gas, liquefied petroleum gas, gasoline, kerosene, diesel, alcohol, soybean oil, coal, wood, cotton, linen, paper and three major synthetic materials (synthetic plastics, synthetic rubber, synthetic fibers), etc.

Combustion. zhùrán

combustion-supporting] a substance that exacerbates the combustion of another substance. For example, sodium nitrate can help sulfur combustion (as the name suggests, a combustible is a substance that exacerbates the combustion of another substance).

It doesn't produce heat, oxygen is combustible and not can be burned directly.

Energy is produced when oxygen is inhaled, and energy is lost when CO2 is exhaled.

Question 1: How many kilograms is a liter of oxygen The oxygen density is , and a liter of oxygen is equal to g, that is, there should be a variety of specifications for industrial oxygen cylinders, for example: Oxygen cylinders Weight:

50 1kg volume: 40l Minimum design thickness: Height:

Straight Dust Diameter: 219mm Specification: 219*

Question 2: How many kilograms is 1 liter of liquid oxygen This question needs to give a specific environment. When the temperature is minus 183 degrees, the density of liquid oxygen is.

Question 3: How many catties is one liter of oxygen? How much does an industrial oxygen cylinder weigh?

The oxygen density is , and the oxygen cylinder is equal to g, that is, the oxygen cylinder used in the industry should have a variety of specifications, for example, under the lead liquid: Oxygen cylinder Weight: 50 1kg Volume:

40L Minimum Design Thickness: Height: Diameter:

219mm Specification: 219*

Question 4: How many kilograms does 1 liter of medical oxygen weigh One liter of medical oxygen weighs one kilogram!

A bottle of oxygen weighs about four kilograms.

Calculation method: A bottle of oxygen for industrial use, the bottle weighs about 70 kilograms, and is filled with oxygen at a pressure of 150 kilograms per square centimeter.

At this time, the oxygen contained is about four kilograms, forty liters of high-pressure cylinders, and a bottle of 120 kilograms of pressure storage gas is 5,800 liters, and the molar volume of oxygen at this time is 256 moles and 256 moles is 4,000 grams, that is, about four kilograms.

Introduction to Oxygen Cylinders:

The oxygen cylinder is a high-pressure container for storing and transporting oxygen blindly, which is generally made of Hesun Zhijin structural steel hot stamping and pressing, with an outer diameter of 219 mm and a commonly used cylinder volume of 40 liters, cylindrical. It is used in hospitals, first aid stations, and nursing homes.

The standard for the storage capacity of an oxygen cylinder is the pressure resistance. The upper limit of the pressure of a conventional oxygen cylinder is 15 megapascals, which translates to 147 atmospheres. The measured value of withstand voltage is MPa. <>

Under standard conditions, it is approximately equal to cubic meters of gaseous oxygen.

Liquid oxygen: It is the liquid in the state of oxygen when it is transported to a liquid state, and it has important applications in the aerospace, submarine and gas industries. Liquid oxygen is a light blue liquid and has strong paramagnetism.

Gaseous oxygen: Oxygen in the form of gas is called gaseous oxygen, and the oxygen in the air is gaseous oxygen, which is colorless, odorless and tasteless under normal conditions.

The weight of a bottle of oxygen is about four kilograms.

Calculation of Reputation Method:

A bottle of oxygen for industrial use, weighing about 70 kilograms, is filled with oxygen at a pressure of 150 kilograms per square centimeter. At this time, the dust contained about four kilograms of oxygen, forty liters of high-pressure cylinders, a bottle of 120 kilograms of pressure storage gas 5,800 liters, at this time the molar volume of oxygen is 256 moles, 256 moles is 4,096 grams, that is, about four kilograms.
