In an change matter chanes in size shape or state without changing identity?
Physical change.
How does matter change without changing it's identity?
Matter can undergo physical changes without changing its identity. Physical changes include melting or freezing; evaporating or condensing; changing shape; chopping or grinding into smaller pieces.
Which of these can vary without changing the identity of an element number?
The mass number can vary without changing the identity of an element, as it represents the number of protons and neutrons in the nucleus. Conversely, changing the number of protons would change the identity of the element, as it defines the element's atomic number.
What is a property of matter that can be observed and measured without changing the matters identity?
One property of matter that can be observed and measured without changing the matter's identity is its mass. Mass is a measure of the amount of matter in an object and can be determined through various methods like weighing.
Is melting crayons a physical property?
Melting crayons is a physical change, not a physical property. A physical property is a characteristic of a substance that can be observed without changing the substance's identity, while a physical change is a change in the substance's appearance without changing its chemical composition.
Is changing direction really the same as changing speed?
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
How do the area and perimeter of the area of a figure change when it's dimensions change?
The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)
What is the difference between physical change ands physical property?
A physical property is any characteristic of a material that can be observed or/and measured without changing the identity.A physical change is the change in which the properties of a substance change but the identity always stays the same.
What is A change in the matter that does not change its identity?
A physical change does not change the identity of matter.
What is the term for a process that does not change the identity of a substance?
Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
Is heat changing water to steam a chemical or physical change?
The process of heat changing water to steam is a physical change. During this transformation, water molecules gain energy and move from a liquid state to a gaseous state, but their chemical composition remains the same (H₂O). In a physical change, the substance alters its form or state without changing its chemical identity.
Can the chemical properties of a substance be observed without changing the substance?
physical properties
