How is vapour fifferent from gas Give examlpe of each.?
Vapor differs from gas in that vapor refers to the gaseous state of a substance that is typically a liquid or solid at room temperature, while gas is a state of matter that exists independently in its gaseous form. For example, water vapor is the gaseous state of water, which is a liquid at room temperature. In contrast, oxygen is a gas that exists as a gas at room temperature and does not have a liquid or solid form under normal conditions.
Why it is not proper to regard gaseous state of amonia as vapours?
Vapor is properly used to refer to a gaseous form of a substance which is liquid or solid under standard temperature and pressure. Because ammonia is a gas at STP, it is not properly called a vapor.
Where are the freezing points and melting points of substances?
They are the same thing. Most commonly the term melting point is used to describe the temperature at which a substance first co-exists in both a liquid and solid state. Freezing point is used usually to describe a substance that is usually liquid at room temperature, such as water. Conversely the term 'boiling point' refers to the first temperature at which the substance exists in both liquid and gaseous states.
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.
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.
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.
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.
What was liquid before liquid?
If a substance that exists in liquid state was not in liquid state then it was in its other states of matter namely solid, gaseous.
Can a liquid substance diffuse in another liquid substance a gaseous in liquid a gaseous in gaseous?
Yes, all of them.
Why it is not proper to regard gaseous state of amonia as vapours?
Vapor is properly used to refer to a gaseous form of a substance which is liquid or solid under standard temperature and pressure. Because ammonia is a gas at STP, it is not properly called a vapor.
Does molten state mean gaseous state?
No, molten state refers to a substance that has been heated to the point of becoming liquid, while the gaseous state refers to a substance in which its particles are free to move without a definite shape or volume. In the molten state, the substance retains its liquid form, whereas in the gaseous state, the substance exists as a gas.
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.
Where are the freezing points and melting points of substances?
They are the same thing. Most commonly the term melting point is used to describe the temperature at which a substance first co-exists in both a liquid and solid state. Freezing point is used usually to describe a substance that is usually liquid at room temperature, such as water. Conversely the term 'boiling point' refers to the first temperature at which the substance exists in both liquid and gaseous states.
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.
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.
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.
