When enough energy is supplied the rigid pattern of molecules is disrupted in?
When enough energy is supplied, the rigid pattern of molecules is disrupted in a phase change, causing the molecules to move more freely. This disrupts the orderly arrangement of the particles and changes the physical state of the substance.
Is nitrogen change states a chemical or physical change?
Changing states of nitrogen, such as from a gas to a liquid, is a physical change because the chemical composition of nitrogen remains the same. It only involves a change in the arrangement of nitrogen molecules.
What are the molecules like before a physical change?
Before a physical change, the molecules of a substance maintain their original structure and composition, but they may have different arrangements or states. For example, in solid ice, water molecules are closely packed and vibrate in place, while in liquid water, they are more loosely arranged and can move past one another. Despite these changes in arrangement and energy, the chemical identity of the molecules remains unchanged throughout the physical change.
Why are changes in state also classified as physical change?
Changes in state, such as melting, freezing, boiling, and condensation, are classified as physical changes because they involve a transformation in the form of a substance without altering its chemical composition. During these processes, the molecular structure remains the same, even though the arrangement and energy of the molecules change. As a result, the substance retains its chemical identity, making these changes purely physical in nature.
Changes of state are considered physical changes because?
Physical changes are changes that don't change the structure of the individual molecules. Though heating a liquid to a gas will change how the molecules are bound to each other, the individual molecules will not change. This is contrasted from a chemical change, where the atoms of the molecules are rearranged.
Is dissolving NaCl in h2o a chemical change?
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.

When ice melts is it a physical change or a chemical change?
It is a physical change. There is no chemical reaction whatsoever.
Why are changes in state also classified as physical change?
Changes in state, such as melting, freezing, boiling, and condensation, are classified as physical changes because they involve a transformation in the form of a substance without altering its chemical composition. During these processes, the molecular structure remains the same, even though the arrangement and energy of the molecules change. As a result, the substance retains its chemical identity, making these changes purely physical in nature.
When water changes to ice the link up of atoms does or does not change?
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
What happens when a physical reaction occurs?
During a physical reaction, the arrangement of atoms and molecules changes, but no new substances are formed. This means that the chemical composition remains the same before and after the reaction. Examples of physical reactions include changes in state (solid to liquid, liquid to gas) or changes in shape.
What does not change when a substance changes matter?
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
Changes of state are considered physical changes because?
Physical changes are changes that don't change the structure of the individual molecules. Though heating a liquid to a gas will change how the molecules are bound to each other, the individual molecules will not change. This is contrasted from a chemical change, where the atoms of the molecules are rearranged.
When energy is absorbed or released is it chemical or physical change?
When energy is absorbed or released, it can be associated with both chemical and physical changes. Chemical changes typically involve the breaking or forming of bonds between atoms, resulting in energy changes, while physical changes involve altering the state or arrangement of molecules without affecting their chemical composition, which can also result in energy absorption or release.
Is the melting of ice is a chemical or physical change why?
Melting ice is a physical change because the properties of the physical changes say that there is a physical change when the state of a material changes. the ice changes into water after melting .this is temporary change as the property says. you can change water back into ice by freezing.
