Which of the following is an extensive property?
The properties that are independent of the mass or size of the system or which does not depend on the amount of substance are known as intensive properties. Hence volume is an extensive property. Was this answer helpful?
What are the two most important properties of all matter?
Matter can be defined or described as anything that takes up space, and it is composed of miniscule particles called atoms. It must display the two properties of mass and volume.
How do the unique properties of water allow life to exist on Earth?
Water’s extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients.
What is the extensive property of oxygen?
Which of the following is an extensive property of oxygen? Boiling point and melting point are extensive properties. Freezing is the change of state of liquid to solid. The density of a substance is an intensive property.
Which of these is an intensive property of matter quizlet?
Think of intensive properties as INdependent, they don’t depend on the mass of the sample. Examples are temperature, color, hardness, melting point, boiling point, pressure, molecular weight, and density.
How do properties of water make life possible?
Water’s polarity allows it to dissolve other polar substances very easily. ‘ The dissolving power of water is very important for life on Earth. Wherever water goes, it carries dissolved chemicals, minerals, and nutrients that are used to support living things.
What are 4 chemical properties of oxygen?
In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. Oxygen is part of a small group of gasses literally paramagnetic, and it’s the most paramagnetic of all. Liquid oxygen is also slightly paramagnetic.
What are the physical properties of oxygen?
Oxygen is a colorless, odorless, tasteless gas. It changes from a gas to a liquid at a temperature of -182.96°C (-297.33°F). The liquid formed has a slightly bluish color to it. Liquid oxygen can then be solidified or frozen at a temperature of -218.4°C (-361.2°F).
What are the 5 unique properties of water?
The five main properties that will be discussed in this article are its attraction to polar molecules, its high specific heat, the high heat of vaporization, the lower density of ice, and its high polarity.
What are the properties and uses of oxygen?
Oxygen is a highly reactive element, highly paramagnetic, and is easily capable of combining with other elements. One of oxygen’s most important chemical properties is that it supports combustion. Oxygen also combines with elements at room temperature, for example, the formation of rust.
What are 2 chemical properties of oxygen?
Chemical Properties of Oxygen At standard temperature and pressure (STP), two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element.

What is Oxygen’s weakness?
Her strengths are that she is able to help people in need, but she can also take oxygen away. Her weaknesses are when she is high up in the air and there is little oxygen in the air, it makes her dizzy.
Why is oxygen so reactive?
Oxygen Exhibits High Reactivity Due to its electronegativity, oxygen forms stable chemical bonds with almost all elements to give the corresponding oxides. The combination of water and oxygen is even more corrosive. Virtually all elements burn in an atmosphere of oxygen or an oxygen-rich environment.
