What is a gaseous substance that is generally a liquid or solid at room temperature?
A lot of substances change state to a gas at room temperature. The most obvious one that springs to mind is Dry Ice (Frozen Carbon Dioxide). This is used a lot in theatrical and movie sets to create the low blanket of swirling fog, which is actually the moisture condensing out of the air due to being cooled to below its Dew Point by the thawing of the Dry Ice.
Another way of asking this question would be "What gases change to a different state when cooled to below room temperature?" The answer to this is "All of them" Depending on how low you cool the air, different gases condense (or in the case of CO2, solidify) as you lower the temperature (assuming constant pressure), in order of decreasing temperature they are Carbon Dioxide (-78.2°C), Oxygen (-183°C), Nitrogen (-196°C) and Hydrogen (-253°C).

What is the random molecular of a substance is greatest when the substance is?
In a gaseous state, as the molecules have the highest degree of freedom to move around and exhibit random motion. This leads to greater randomness in the distribution of molecular positions and velocities, resulting in a higher entropy compared to when the substance is in a liquid or solid state.
What is the temperature at which a given substance will change from a solid into a liquid?
The temperature at which a substance changes from a solid to a liquid is called its melting point. It is a specific temperature unique to each substance and is determined by the intermolecular forces within the substance. When the substance reaches its melting point, the solid will begin to transition into a liquid state.
What is the only substance thatexest as a solid liquid and gasses in the earths atmosphere?
Water is the only substance that commonly exists as a solid, liquid, and gas in Earth's atmosphere. Solid water is ice, liquid water is water, and gaseous water is water vapor.
What is the state of matter of hydrogen chloride at room temperature?
Hydrogen chloride is a gas at room temperature and pressure.
When changing from a solid to a liquid the magic temperature for the substance is called?
The magic temperature for a substance where it changes from a solid to a liquid is known as its melting point. This is the temperature at which the solid gains enough thermal energy to overcome its attractive forces and transition into a liquid state.
What is the gaseous form of a substance which exist as a liquid at room temperature known as?
The gaseous form of a substance that exists as a liquid at room temperature is known as vapor.
What does vapor describe?
Vapor typically refers to a substance in gas form that is typically at a lower temperature than its boiling point. It can also refer to the gaseous state of a substance that is normally a liquid or solid at room temperature.
Can a liquid substance diffuse in another liquid substance a gaseous in liquid a gaseous in gaseous?
Yes, all of them.
What is the gaseous form of a substance which exists as a liquid at a room temperature known as?
You think to vapours of a liquid.
What is the substance of boiling point?
The boiling point of a substance is the temperature at which it changes from liquid state to gaseous or vapor state.
What temperature at which a substance in the liquid phase transforms to the gaseous phase refers to the substances?
The temperature at which a substance in the liquid phase transforms to the gaseous phase is called the boiling point for pure substances. It is a characteristic property of the substance and remains constant under a specific pressure.
What is the tripple point of a substance?
The temperature AND pressure at which the solid, liquid, and gaseous state can all coexist.
When is a substance in the gaseous phase called a vapor?
A substance is called a vapor when it is in the gaseous phase at a temperature below its critical temperature. Above this critical temperature, the substance is in the supercritical fluid phase rather than a distinct gas and vapor phases.
Which substance in the gaseous state should be calleda vapour?
A substance in the gaseous state that is typically a liquid or solid at room temperature can be referred to as a vapor. Examples include water vapor or steam, which is the gaseous state of water.
Is gas a form of matter that is generally a liquid or solid at room temperature?
Neither. A gas is a form of matter that is generally gaseous at room temperature.
Temperature a substance will change from liquid to gas?
The temperature at which a substance changes from liquid to gas is known as its boiling point. At this point, the vapor pressure of the liquid equals the atmospheric pressure, allowing it to overcome intermolecular forces and transition to a gaseous state.
Temperature at which a substance boils?
Every substance has their own boiling point.
