Why vapour are same as gas?
Vapour and gas are not same.A substance which under ordinary conditions is a solid or a liquid,but under specific conditions is gaseous is called a vapour. For example,water vapour,sulphur vapour,etc. However, a substance which under ordinary conditions is gaseous ,is called a gas. for example,Oxygen,Nitrogen,etc
True or false the temperature of a substance changes during a change in state?
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
When a substance from any state of matter to another is called a?
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
What causes a substance to change its state of matter?
A substance changes its state of matter when the temperature or pressure it is exposed to reaches a critical point for that particular substance. When these conditions are met, the particles within the substance gain or lose energy, causing them to either move further apart (melting, vaporization) or closer together (freezing, condensation).
What is the condensation rate formula used to calculate the rate at which a substance changes from a gas to a liquid under specific conditions?
The condensation rate formula is typically calculated using the equation: Condensation Rate (Pvapor - Pliquid) / R Where: Pvapor is the vapor pressure of the substance Pliquid is the pressure of the substance in its liquid state R is the gas constant This formula helps determine how quickly a substance transitions from a gas to a liquid under specific conditions.
What will not change the state of matter?
Factors such as the amount of a substance, its chemical composition, and the presence of impurities will not change its state of matter. For instance, heating or cooling a substance can change its state (e.g., solid to liquid), but simply having more or less of the same substance at the same temperature and pressure will not alter its state. Additionally, the state of matter remains unchanged as long as the temperature and pressure conditions stay constant.
Does argon change in state of matter?
Argon is a noble gas that remains in the gaseous state at room temperature and pressure. It does not change state easily under normal conditions.
Why vapour are same as gas?

What is the phase change from solid to gas?
Sublimation is the phase change from solid to gas, where a substance transitions directly from a solid state to a gas state without passing through the liquid state. This process typically occurs under specific temperature and pressure conditions, where the solid's vapor pressure exceeds the ambient pressure.
What are two physical properties that can vary even when the substance with these properties dose not change?
Density and color can vary while the substance remains the same. Density is mass per unit volume, which can change depending on pressure or temperature. Color can vary due to factors such as lighting conditions or impurities in the substance.
What is the change of a substance from one physical state to another?
change of state
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
A substance that will not become a gas under existing conditions?
A substance that will not become a gas under existing conditions is likely in a solid or liquid state. These substances have strong intermolecular forces that prevent them from easily transitioning into a gas phase. Examples include metals, water, and many organic compounds.
True or false the temperature of a substance changes during a change in state?
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
When a substance from any state of matter to another is called a?
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
What does a substance change in a physical change?
One possibility is a change in state.
What is the change of a substance from one physical change to another?
change of state
