In what ways do vapors and gases differ and how can these differences be distinguished?
Vapors and gases differ in their physical states and how they are formed. Vapors are substances in a gaseous state that are typically created from liquids or solids at a specific temperature and pressure, while gases exist naturally in a gaseous state. These differences can be distinguished by their origins and conditions under which they exist.
Why are covalent substances gases and liquid rather than solids?
Covalent substances have weaker intermolecular forces compared to ionic or metallic substances, which makes them more likely to exist as gases or liquids at room temperature. The lower strength of the bonds allows the molecules to move freely and overcome the forces that hold them together as solids.
Which substances exist in air?
Air contain nitrogen, oxygen, other minor noble gases, ozone, carbon dioxide water vapors, fumes, powders.
What gases can exist at 70 degrees Fahrenheit?
At 70 degrees Fahrenheit, gases such as oxygen, nitrogen, carbon dioxide, and helium can exist in their gaseous state. The specific gases present will depend on the surroundings and conditions at that temperature.
How conductive are monatomic substances?
Monatomic substances, such as noble gases, have low conductivity because they have very few free electrons available for conduction. This is because monatomic substances exist as individual atoms rather than being bonded in a lattice structure like metals.
Are solids gases and liquids substances?
Yes, all are substances.
What phase is present at room temperature and normal atmospheric pressure?
At room temperature and normal atmospheric pressure, most substances exist in either the solid or liquid phase. Some exceptions include noble gases like helium and neon, which exist as gases at these conditions.
The term gas is limited to those substances that exist in the gaseous state at?
The term gas is limited to those substances that exist in the gaseous state at room temperature and pressure. This means they have low density, take the shape of their container, and have molecules that are far apart. Gases can be compressed and expand to fill their container.
How do you explain the of gases?
Gases are substances with very weak bonds between molecules.
Many elements found in nature exist as?
The chemical substances found in the atmosphere exist as gases.
Do gases exist in ice?
yes it does
What is the characteristics of covalent substances?
Covalent substances are made up of molecules held together by covalent bonds, where atoms share electrons. These substances tend to have lower melting and boiling points compared to ionic compounds, and they are typically nonconductors of electricity in their solid state. Covalent substances can exist in various forms, including gases, liquids, and solids.
