    The melting point is -218 degrees and the boiling point is -183 degrees, that is, at temperatures above -183 degrees, oxygen is gaseous. Only between -218 and -183 degrees does oxygen be liquid. 200 degrees is much higher than its boiling point, so it is gaseous.

    At room temperature and pressure, oxygen is a colorless and odorless gas; Melting point, boiling point, gas density grams.

    Hence oxygen is gaseous at 200 degrees Celsius.

    Additional note: Oxygen, atomic number 8, atomic weight, element name** in Greek, originally meaning "acid former". In 1774, the British scientist Priest used a lens to focus sunlight on mercury oxide and discovered a gas that could strongly help combustion.

    Lavoisier studied this gas and correctly explained its role in combustion. Oxygen is the most abundant and widely distributed element in the earth's crust, and its content in the earth's crust is: Elemental oxygen accounts for 23% of the atmosphere.

    There are three stable isotopes of oxygen: oxygen-16, oxygen-17, and oxygen-18, with oxygen-16 being the most abundant. Except for inert gases, halogens and some inactive metals that need to be indirectly oxidized to form oxides, all other metals and non-metals can directly interact with oxygen to form oxides.

    The most abundant oxides are water and silica. Oxygen can also form peroxides and superoxides with reactive metals. Oxygen is not only an indispensable substance for animal life maintenance processes and combustion processes, but also plays an important role in modern industrial production.

    The critical temperature of oxygen is about minus 120 degrees Celsius, and no amount of pressure can liquefy oxygen.

    At one atmosphere, the temperature of liquid oxygen is -183 to, above -183 becomes gas, below which it becomes solid.

    The temperature of liquid oxygen is -183; Cooling to a blue solid state It's not like the upstairs says that no amount of pressure can liquefy oxygen.

    The liquid state is more than minus 100 degrees, about minus 120, and the freezing point of liquid oxygen:

    What is the boiling point of liquid oxygen, right?

    Liquid oxygen is light blue, and the temperature of liquid oxygen is -183; Cool to become a blue solid. When the concentration of oxygen in the air reaches a certain proportion, it can promote combustion (combustion) and cannot spontaneously combust. City gas dust transport (65%) and oxygen are mixed, and the flame temperature can reach 2730 when burning

    Liquid oxygen is associated with organic matter and oxidizes easily.

    Liquid oxygen has a boiling point of -183 and cools to a snowflake-like, pale blue solid.

    So, the temperature of liquid oxygen is between -183 to.

    Under standard conditions (0,101 kPa), the molar volume of the gas is 31,250 mol for 1 ton of liquid oxygen, which is multiplied by 700,000 liters or 700 cubic meters. At room temperature (25) and 101 kPa, the molar volume of the gas is 31,250 mol for 1 ton of liquid oxygen, which is multiplied by 765,625 l, that is, cubic meters. The density of liquid oxygen is .

    The density of liquid oxygen can be calculated as follows: p= kg l

    When t=-183, p=

    Then at -183, the volume of 1 ton of liquid oxygen is cubic meters.

This is because when you are burned by water vapor at 100 degrees Celsius, the water vapor turns into liquid water (still 100 degrees Celsius), and a large amount of heat (heat of vaporization of water) ...... is releasedSo it's worse than being scalded by water at 100 degrees Celsius.

If two cups are the same size, the 50-degree water freezes first. Water at 50 degrees absorbs half the heat energy of 100 degrees, and when it is exothermic at the same time, the water at 50 degrees first reaches 0 degrees, and then continues to exothermic and begins to freeze. Hope you are satisfied.
