Is evaporation a physical chqnge?
Yes, evaporation is a physical change. It is the process in which a liquid changes into a gas without changing its chemical composition, only its physical state.
The phase change in which a substance change from a solid to a gas or vapor without changing to a liquid first is?
Sublimation is the phase change in which a substance changes from a solid directly to a gas or vapor without passing through the liquid phase. This process occurs when the substance's vapor pressure exceeds that of its solid form at a particular temperature.
When a liquid changes into a gas what kind of physical change has occurred?
When a liquid changes into a gas, it undergoes a physical change known as vaporization or evaporation. This change involves the molecules in the liquid gaining enough energy to overcome the intermolecular forces holding them together and escape into the gas phase.
When gold changes from a solid to a liquid is that a physical or chemical change?
The change from a solid to a liquid is a physical change, as the substance's chemical composition remains the same. Physical changes affect the state or form of matter without altering its chemical composition.
Can you see a physical change?
Yes, physical changes involve a change in the appearance or form of a substance without changing its chemical composition. Examples include changes in state (solid to liquid), size or shape, or appearance (cutting paper).
Is boiling does that changes as a physical or chemical?
Boiling is a physical change because the substance is changing from a liquid to a gas without changing its chemical composition.
Is changing from a gas to a liquid a chemical change?
No, changes of state such as this are physical changes.
Melting sugar is an example of a?
physical change. When sugar is heated, it changes from a solid to a liquid state without changing its chemical composition.
What do you call it when a solid changes to a gas without changing to a liquid first?
Sublimation
What changes a solid to a gas or vapor without changing to a liquid?
Iodine I2
Is a change that alters the form of a substance without changing it into another substance is called what?
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first is?
Sublimation is the phase change in which a substance changes from a solid to a gas or vapor without first becoming a liquid. This process occurs when the pressure and temperature conditions allow the solid to transition directly into a gas.
What type of phase change is happening as a solid changes to gas without becoming to a liquid?
Sublimation occurs when solid changes directly to liquid without changing to solid state. Applying pressure and reducing temperature can liquefy gases.
Is freezing a physical change?
Yes, freezing is a physical change because it is a reversible process where a substance changes from a liquid to a solid state without changing its chemical composition.

Is evaporation a physical chqnge?
Yes, evaporation is a physical change. It is the process in which a liquid changes into a gas without changing its chemical composition, only its physical state.
Which phase change does not involve changing a liquid into a gas?
The liquid to gas phase change is vaporizing; the reverse is condensing. The other phase changes are: - solid to liquid: melting - liquid to solid: freezing - solid to gas: sublimation - gas to solid: deposition
