What else can I help you with?
Are physical changes chemical reactions?
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
Changes in properties of matter are called?
physical or chemical changes
Is liquid to gas chemical change?
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
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 occurs more often on earth physical or chemical changes?
Both physical and chemical changes occur frequently on Earth. Physical changes involve a change in the state or appearance of a substance without altering its chemical composition, such as melting ice or boiling water. Chemical changes involve a transformation at the molecular level, resulting in the formation of new substances, such as rusting of iron or digestion of food. Both types of changes play essential roles in Earth's natural processes and cycles.
What are facts about physical and chemical change?
Chemical changes take place on the molecular level
Can an object undergo both physical and chemical changes?
Yes, an object can undergo both physical and chemical changes. Physical changes involve changes in physical properties like shape, size, or state of matter without altering the composition. Chemical changes involve a transformation at the molecular level, resulting in the formation of new substances.
Are physical changes chemical reactions?
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
Is slicing an apple is a chemical change or a physical change?
This is a physical change. You only change the shape and size of an apple by slicing it. Chemical changes would mean changing the molecular composition of the apple.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What kind of changes is it chemical or physical and why?
a physical change is a phase change, such as water to ice or water vapor. a chemical change takes place on a molecular level, producing a new substance.
Is water condensing a chemical change?
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.
Changes in properties of matter are called?
physical or chemical changes
Can matter undergo changes in both its physical and its chemical properties Explain please?
Yes, matter can undergo changes in both its physical and chemical properties. Physical changes involve alterations in the form or state of matter without changing its chemical composition, such as melting ice into water. Chemical changes, on the other hand, involve transformations at the molecular level, resulting in the formation of new substances with different chemical properties, such as rusting of iron.
Is liquid to gas chemical change?
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
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.
Does freezing alcohol change its molecular structure?
No because physical states of matter changes are physical changes. they are not chemical changing meaning it is still alcohol, just frozen.
