A substance is known to be liquid at room temperature if its melting point is below room temperature (typically around 20-25°C). This means the substance will exist in a liquid state under normal room conditions.
the only liquid is water all other are aquious solutions and to find out wich you write a balanced equations
The above answer is NOT True. Liquid is just one state of matter. All Elements can be in a LIQUID State at the appropriate TEMPERATURE. For example Mercury is a METAL that is a Liquid at room temperatures. Chemical Compounds can also be Liquids at appropriate temperatures.
Matter can have 4 states:
1. Solid
2. Liquid
3. Gas
4. Plasma
Knowing the boiling temperature of water at normal conditions : 1000C
Take a sample of your liquid, but it in a beaker with volume marks, note the volume.
Take a big cooker of water, boil it, put your beaker of sample inside.
- If the volume doesn't change => your sample consists water or water with other liquid with higher boiling temperature or no water.
- If the volume decreases
+ if decrease to a definite volume and stop decreasing: now you have only water, the other liquid has lower boiling temperature.
+ if decrease to volume zero: you don't have water in your sample.
Those're some simple situations.
There are a number of ways in which you could identify a liquid. You could identify a liquid based on freezing temperature for example.
By its boiling point, freezing point (or melting point), and its density
Measure its boiling point. All pure substances have their own unique boiling point.
A liquid takes up the shape of the container that it is poured into.
You look up its melting point and its boiling point, and if its mp is below room temp and bp is above room temp it should be liquid

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 physical state is carbon tetrachloride at room temperature?
It is a liquid because at room temperature the molecular structure of the substance wants to expand. When the substance expands it goes from being a solid to a liquid. This expansion takes place when the room is at the commonly know "room temperature"
What is sucrose solid or liquid at room temperature?
Sucrose is a solid at room temperature. It is a crystalline substance that is commonly known as table sugar.
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.
Is decane a liquid or solid at room temperature?
Decane is a liquid at room temperature.
How does a substance's boiling point determine its state at room temperature?
A substance's boiling point indicates the temperature at which it transitions from a liquid to a gas. If the substance's boiling point is below room temperature, it will be a gas at room temperature. If the boiling point is above room temperature, it will be a liquid at room temperature.
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 is A metal substance that is a liquid at room temperature?
The element mercury.
How can a substance be frozen at room temperature?
A substance can be frozen at room temperature if its freezing point is below the temperature of the room. This can happen with certain substances like liquid nitrogen or dry ice, which have very low freezing points and can transition from a liquid to a solid state at room temperature.
What physical state is carbon tetrachloride at room temperature?
It is a liquid because at room temperature the molecular structure of the substance wants to expand. When the substance expands it goes from being a solid to a liquid. This expansion takes place when the room is at the commonly know "room temperature"
How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
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 physical state of a substance whose melting point is below the room temperature?
A substance with a melting point below room temperature would typically be in a solid state at room temperature. However, it may start to melt or become a liquid as the temperature increases.
Is mercury a liquid at room temperature?
Yes. If you are talking about the thing in thermometers, yes, they are liquid.(metal- liquid) Mercury is one of the few metals that is a liquid at room temperature. Other metals, as you know, are solid at room temperature.
What does state at room temperature mean?
It means whether the substance in question is solid, liquid or gas at normal room temperature, so you could assume that about 20 degrees celsius. Oxygen is a gas at room temperature Water is a liquid at room temperature Iron is a solid at room temperature.
What is sucrose solid or liquid at room temperature?
Sucrose is a solid at room temperature. It is a crystalline substance that is commonly known as table sugar.
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.
