Physical because in chemical change two liquids have to mix and the result should be solid.
Chemical changes are color changing, gases coming out, temperature by temperature i mean
whether is it hot or not, and whether its solid or not.
============================
What ? ? ?
"Odorless" is not a change at all.
It's a description, an adjective, like 'blue', 'loud', 'short', 'heavy',
'funny', 'slow', 'happy', 'reasonable', 'dark', 'soft'.
None of those is a change either.
Odor is a chemical property.
it's the physical and chemical characteristics of oxygen!
Helium doesnot have a gender. It is a chemical element
Natural gas for cooking mainly exhibits physical properties. It is a colorless and odorless gas that burns cleanly when ignited. It does not undergo significant chemical changes during the cooking process, but rather releases energy as heat.
argon is a colorless, odorless, tasteless, gas
Yes, most of smells come from esters which can be derived from carboxylic acids, but they also come from adlehydes, ketones, alcohols, and terpenes. These smells get stronger with the greater amount of carbons in a chain or ring. Low molecular weight esters give fruits their odors and flavors while carboxylic acids have a more acrid and repellent stench. All of this is organic chemistry.
Yes hydrogen is a colorless odorless gas, it is the the first chemical element on the periodic table and the most reactive.
Carbon dioxide (CO2) is a chemical compound consisting of one carbon atom bonded to two oxygen atoms. It is a chemical property because it describes the composition and arrangement of atoms in a substance. However, in terms of physical properties, carbon dioxide is a colorless, odorless gas at standard temperature and pressure.
The freon itself is odorless, although the oil in the system does have an odor.
The chemical make up of odorless charcoal lighter fluid includes methanol or ethanol.
Xenon is a colorless, odorless, and heavy gas with a density greater than air. It is relatively inert chemically, and has the ability to form compounds with other elements under specific conditions. Xenon exhibits a range of oxidation states in its chemical compounds and is used in various applications such as in lighting, anesthesia, and electronics.
