What happens when something reaches absolute zero?
At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale. Physicists have now created an atomic gas in the laboratory that nonetheless has negative Kelvin values.
What determines the state of matter of a substance?
The amount of energy in molecules of matter determines the state of matter. Matter can exist in one of several different states, including a gas, liquid, or solid state. A gas is a state of matter in which atoms or molecules have enough energy to move freely.
What two things does the state of matter of a substance depend on?
These are the three common states of matter. Whether a substance is a solid, a liquid, or a gas depends on its temperature and the pressure placed on it. At room temperature (about 22°C) and at the normal pressure exerted by the atmosphere, water exists as a liquid, which can flow from one container to another.
How many forms of matter is there?
five phases
What is the relationship between matter and elements?
The term matter refers to anything that occupies space and has mass—in other words, the “stuff” that the universe is made of. All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions.
What is the basic units of matter contained in common salt?
Chemically, table salt consists of two elements, sodium (Na) and chloride (Cl). Neither element occurs separately and free in nature, but are found bound together as the compound sodium chloride.
What are the parts of matter smallest to largest?
smallest to largest: compounds, electrons, elements, protons, and. neutrons.
What is the smallest subatomic particle and where is it located?
Quarks. Quarks represent the smallest known subatomic particles. These building blocks of matter are considered the new elementary particles, replacing protons, neutrons and electrons as the fundamental particles of the universe.
