When a liquid changes into a gas what kind of physical change has occurred?
A liquid changing into a gas is called evaporation.
The phase change in which a substance change from a solid to a gas or vapor without changing to a liquid first is?
it is sublimation
In a physical change a substance changes its but not its identity?
A physical change alters a given material without changing its chemical_____?
Why considerable heat energy is needed to convert 1g of water into 1g of steam at 100c without any change in temperature taking place?
There is heat needed to transform the configuration of liquid water to gaseous state. This is change of state energy changes the configuration without changing the temperature.
What changes shape but doesn't change volume?
A gas can change shape but it doesn't change volume, a liquid also changes shape but doesn't change volume.
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 changing from a gas to a liquid a chemical change?
No, changes of state such as this are physical changes.
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
When a liquid changes into a gas what kind of physical change has occurred?
A liquid changing into a gas is called evaporation.
Solid changing into vapor is called?
When a solid changes directly into a vapor without passing through the liquid state is a physical change called sublimation.
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.
What is sublimaton?
Submilation is when you change something directly from a gas to a liquid, with out changing it into a liquid first.

What is changing state?
A change of phase, from solid to liquid, or liquid to gas, or gas to liquid, etc., is also sometimes called a change of state.
Why liquid water changing into steam is a physical not a chemical change?
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
