How do the physical properties of rust compare with the physical properties of iron and oxygen?
For example, the ability of iron to rust can only be observed when iron actually rusts. When it does, it combines with oxygen to become a different substance called iron oxide. Iron is very hard and silver in color, whereas iron oxide is flakey and reddish brown.
How is oxygen a gas?
Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature.
Which of the following is a physical change?
The correct answer is Melting of ice. Among all the given options, Melting of ice involves a physical change. A physical change involves the changes of state from a solid to a liquid or a gas and vice versa. Boiling water, Ice melting into water is an example of this conversion.

What are the physical properties of carbon dioxide?
Physical properties
Carbon dioxide is colorless. At low concentrations the gas is odorless; however, at sufficiently high concentrations, it has a sharp, acidic odor. At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m3, about 1.53 times that of air.
Can oxygen burn?
Oxygen is not flammable, but it can cause other materials that burn to ignite more easily and to burn far more rapidly. The result is that a fire involving oxygen can appear explosive-like.
Where is oxygen found kids?
Interesting facts about oxygen
Oxygen is literally everywhere—it’s not only in the atmosphere and the air around you, but it’s also in rocks and dirt, in the ocean, and even in the sun. 50% of the Earth’s crust is filled with oxygen, and the oxygen in the sun helps it burn.
How much oxygen is in the human body?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
How do you identify physical properties?
Physical properties are those general properties you notice most readily about a substance, such as its size, state of matter (solid, liquid, or gas), color, mass, density and strength. Values for physical properties can be determined by tests that don’t alter the substance being tested.
