What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
What kind of changes in substances are always physical changes?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
What happens at the molecular level when a substance boils?
The state of matter changes from a liquid to a gas. (But the one word answer that the assignment is looking for is vaporization.)
How does an increase in temperature account for the fact that substances change state?
An increase in temperature changes the state because it melts it
What happens when you turn solid into liquid into a gass?
These are changes in physical state, which are physical changes.
What happens when matter is changed physically?
It means that although it changes, no new substances are formed. Examples of such changes are melting and other state changes, and dissolving.
How substances changes from one state to the other state?
through changes of energy
How are the state changes of water similar to the state changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
How are the state changes of similar to the states changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
What kinds of changes in substances are always physical change?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
How does matter physically change when it changes its phase or state?
Its motion changes speed on the molecular level

What kind of changes in substances are always physical changes?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
What happens to water as it changes state?
The density changes.
How molecular motion changes as a substance changes from one state to another?
Molecular motion is less constrained in liquid than in solid and is less constrained in gas than in liquid.
How are the states changes of water similar to the state changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
What does change of state operation?
Change of state is a property that involves the substances of chemical and physical changes
