What else can I help you with?
Is it true that metals can be solids liqids and gases?
Yes. Mercury is a metal at room temperature. And at sufficiently high temperatures, all metals will become gases.
What are noble gases in room temperatures?
Noble gases at room temperature are chemically inert and non-reactive. They include elements like helium, neon, argon, krypton, xenon, and radon. They are colorless, odorless, and tasteless, and exist as monatomic gases.
How do gases condense?
Gases are condensed at low temperatures.
How do gases behave under different pressures and different temperatures?
Gases behave differently at different pressures and temperatures. At low pressures, gases expand to fill the available space. At high pressures, gases become more compact. At low temperatures, gases condense into liquids or solids. At high temperatures, gases expand and exert greater pressure.
Do gases also contract and expand with changing temperatures?
Yes,gases also contract and expand with changing temperatures
Are hydrogen and oxygen gases at room temperature?
Yes. Both are gases at room temperature.
What are most nonmetals at room temperature?
Most nonmetals are gases at room temperature, such as oxygen, nitrogen, and fluorine. Some nonmetals, like sulfur and carbon, are solids at room temperature.
Are lanthanides gases at room temperature?
No, lanthanides are not gases at room temperature. They are a group of metallic elements that are solid at room temperature.
Are most nonmetal gases at room temperature?
Yes, most nonmetal gases are typically at room temperature. Examples include oxygen, nitrogen, and fluorine, which are all gases at room temperature.
Are all halogens gases at room temperature?
No, not all halogens are gases at room temperature. Fluorine and chlorine are gases at room temperature, bromine is a liquid, and iodine is a solid.
Are at low temperatures ideal gases liquefy?
At low temperatures, ideal gases can liquefy if they are cooled below their critical temperatures. At temperatures below the critical temperature, the gas will condense into a liquid due to the decreased molecular motion and intermolecular forces becoming dominant over kinetic energy.
Is a element a gas at room temperature?
It depends on which element we are talking about. Some elements, like oxygen and nitrogen, are gases at room temperature, while others, like mercury and bromine, are liquids, and some, like gold and silver, are solids.
