What happens to the identity of a substance when it makes a physical change?
there is to types of change to a substance chemical and physical in a physical change the result is a mixture also most times you can change your end result into what you started with e.g.freeze-melt evaporate-condesate
Is flour dissolving in water a physical or chemical change?
It is a physical change because it is still there and in the same form, just smaller. YOu can separate it from water if you want to which makes it physical.
What kind of change makes a substance feel different but does not change its elemental composition?
A physical change (e.g. ice melting to become water)
What is different between physical change and chemical change?
A physical change stays the same like tearing paper A chemical change makes the substance something new like fireworks explode (fireworks change to explosion)

What is an example of a physical change that makes the substance disappear?
Evaporation, as when water is boiled. It changes phase, from a liquid to water vapor, a gas which is invisible.
Is the glowing of a platinum wire in a flame a physical or chemical change?
It is a physical change. A physical change involves changing a substance only in its appearance, smell, taste, feel, or sound. A chemical change involves changing what makes up the substance or the way the substance reacts with other substances. When a normal platinum wire is placed over a flame, it glows. This is a physical change because the things that make up the platinum have not been changed, but the appearance has changed.
When a change makes a new substance you say a - has taken place?
A chemical reaction makes a new substance.
Is it correct to say that dissolving a packet of juice powder in water makes a new substance such as fruit punch so it must not be a physical change?
The change is a physical one because the powder is simply dissolving into the water, and it could be powdered again by removing the water again. The physical properties of the fruit punch are very different, but not a chemical change unless there is a new substance created or precipitated.
What makes a new substance?
a chemical change
Whats a physical change?
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
Is boiling butter a physical change?
Making butter involves the materials in a mixture to be separated. This makes the process of making butter a type of physical change.
