Taken alone as pure oxygen, it will first respond as an ideal gas if the beginning pressure and temperature are not to great. It will expand with increased temperature or if restrained will build pressure. This comes from Charles' Law and the Ideal Gas Law. When heated to very high temmperature oxygen will ionize like gas in a florescent light, changing to a plasma. Many materials are capable of this process. Low pressures are required to accomplish this generally.
Sulfur heated in oxygen produces a blue flame.
When copper is heated in oxygen, the compound formed is copper oxide.
A chemical reaction happens when mercury is heated and reacts with oxygen. This reaction results in the creation of mercuric oxide, an orange or red compound.
When Hg2+ (mercury oxide) is heated it creates both Hg (liquid mercury) and O2 (oxygen gas)
When mercuric oxide is strongly heated in a hard glass tube, it decomposes, globules of mercury collect in the cooler part of the tube and oxygen gas is evolved. It may be collected over mercury in a pure and dry state.
Ozone when heated gets decomposed. It decomposes into oxygen.
Decomposed to produce PbO and oxygen gas!
Nothing unless they are heated. If they are heated it will become iron oxide. Which is the same material that we find the ground
When copper is heated it oxidizes. The additional oxygen molecules it takes on when oxidizes leads it to have a higher mass.
When water is heated, it loses its ability to hold dissolved oxygen. This means that as the water temperature increases, the amount of oxygen available for aquatic organisms decreases. This can lead to lower oxygen levels in the water, which can be harmful to aquatic life.
When liquid oxygen is heated, it undergoes a phase change and turns into gaseous oxygen. As it heats up and transitions into a gas, its volume expands significantly. This increase in volume leads to an increase in pressure, potentially causing the container to rupture if not properly controlled.
Sulfur heated in oxygen produces a blue flame.
When magnesium is heated in air, it reacts with oxygen to form magnesium oxide. The total mass of the system, which includes the magnesium and the oxygen it reacts with, remains the same according to the Law of Conservation of Mass.
When potassium dichromate (K2Cr2O7) is heated, it decomposes into potassium chromate (K2CrO4) and oxygen gas (O2) is released. The color of the compound changes from orange to yellow as it loses oxygen atoms during the decomposition process.
When copper is heated in oxygen, the compound formed is copper oxide.
When matter is heated it will expand
When ice is heated, it melts into water and eventually evaporates into steam as it reaches its boiling point. When magnesium is heated, it undergoes a chemical reaction with oxygen in the air to form magnesium oxide and emits a bright white light.
