By changing the size, shape, or amount of a given substance, a physical change is being exerted. A physical change is a change in which the molecular structure of the substance remains the same. For a substance to be considered "changed", a chemical reaction must take place resulting in a reconfiguration of molecules. For example, with enough heat, wood undergoes a chemical reaction, converting it to carbon. Chipping a log with a hatchet, on the other hand, would entail a physical change.

When matter undergoes a physical or chemical change the amount of mass changes or stays the same?
In physical changes, the amount of mass stays the same because no new substances are formed. In chemical changes, the amount of mass stays the same due to the law of conservation of mass, which states that mass cannot be created or destroyed, only rearranged into different substances.
What happens to a substances temperature during a phase change?
stays the same
Does the composition stays the same or pure substance?
A pure substance consists of only one type of element or compound. The composition of a pure substance always stays the same, with a fixed ratio of its constituent particles.
What is the heat energy needed to change a liquid to gas while the temperature stays the same?
The heat energy needed to change a liquid to gas while the temperature stays the same is called the heat of vaporization. This energy is used to overcome the intermolecular forces holding the liquid molecules together and convert them into a gas. It is a phase change process that occurs at the boiling point of the substance.
What happens to the volume of a liquid when it is poured into a container with a different shape?
Well, honey, the volume of the liquid stays the same no matter what shape container you pour it into. It's like trying to fit into a new pair of Spanx - your size doesn't change, just the way it's all squished in there. So, whether it's a cylinder, a cube, or a unicorn-shaped container, that liquid ain't gonna magically multiply or disappear.
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
When a substance changes form but it remains the same substance is it a chemical or physical change?
it would be physical change because physical change is when the substance stays the same
When a substance changes form but it remains the same substance is it a physical or chemical change?
it would be physical change because physical change is when the substance stays the same
Which stays the same when a substance switches from liquid to gas?
During the phase change, the temperature stays the same.
What stays the same in a physical change?
The chemical nature/identity of the substance stays the same when a physical change takes place.
What is physical changing?
A physical change changes the property of a substance without changing the substance completely. In other words, a physical change is reversible.This change that occurs in the physical property/properties of a substance without altering its composition. A physical change:Possibly canchange withstate of matter (sublimation, decomposition, evaporation, melting, freezing, and condensation).No new material is formed.Possibly can dissolve.Possibly can occur either by increasing or decreasing the temperature.Is reversible.A physical change is any change not involving a change in the substance's chemical identity.a physical change is the color shape taste and smell of a substance.A physical change is where an object changes is size/ shape
What is the substance that undergoes a physical change but always stays the same?
a physical change is totally reversible, i.e, you can get the substance you will get back after some physical process like heating, evaporating, etc. thus the substance actually remains the same.
What happens to the mass of 2 Substance when mixed to form a Solution?
I think it stays the same. I'm trying to figure this out as well. My friend told be it stays the same.
When chewing gum does the volume change?
No, the volume stays the same, the chewing gum just changes its shape/
When matter undergoes a physical or chemical change the amount of mass changes or stays the same?
In physical changes, the amount of mass stays the same because no new substances are formed. In chemical changes, the amount of mass stays the same due to the law of conservation of mass, which states that mass cannot be created or destroyed, only rearranged into different substances.
What states that during any change the amount of energy stays the same?
Law of Conservation of Energy.
What is the type of matter change in which matter stays the same and no new substances are formed?
A physical change is a type of matter change in which the substance's chemical composition remains the same, and no new substances are formed. Examples of physical changes include changes in state (solid to liquid), changes in shape, or changes in size.
