What is physical change in matter?
A physical change is a change to a substance/object which can be easily reversed, and no new substance is formed from it (as opposed to chemical change). The state of matter is usually changed, for example, turning from a solid to a liquid. e.g. ice cube melting
A physical change is best defined as?
a process that does not change the chemical composition of a substance. A change in a substance with no new substances being formed
Why does the density of an object never change?
1 I'm not sure that this is true-- at least without some qualifications. If an object's shape is changed in such a way that it will enclose one or more pockets of air, some other substance, or even vacuum, the object's over-all density may change. If no pockets are formed, then the density probably is not changed 2 Density is the ratio of mass to volume.
Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
What are signs a physical change has occured?
change in the form -in general can be indicated for the physical form. The substance may dissolve or its stage may change. If the change is physical, it should be reversable.
Is density a physical or chemical change or is it a physical and chemical change?
Your answer will be physical property.It can also be physical change when you're telling the density of an object. And the reason why is "density" is... physical is just those kind of stuff...
In a chemical change what substance is formed?
The substance formed in a chemical change is called Product.
What can be observed only when a substance is changed to another substance?
Changes in physical properties such as color, texture, or density, as well as changes in chemical properties such as reactivity or toxicity, are observed when a substance is changed to another substance. New chemical bonds, molecules, or structures may also be formed during the transformation.

Is water into ice is physical change?
Yes it physical change. physical change is a change that expressed as no new substance with new composition is formed. when water is changed in to ice there is no new substance with new composition formed.the only change is only water particles are compacted to form the solid ice.
When a new substance is formed it is a physical change?
no
When a physical changes occurs new substance are formed?
False. In a physical change, the substance remains the same even though there may be a change in appearance or state. The molecules of the substance do not rearrange themselves to form a new substance.
Why does changing the the shape of an object have no effect on the density of that object?
1 I'm not sure that this is true-- at least without some qualifications. If an object's shape is changed in such a way that it will enclose one or more pockets of air, some other substance, or even vacuum, the object's over-all density may change. If no pockets are formed, then the density probably is not changed 2 Density is the ratio of mass to volume.
Is ripening mango is physical change?
yes it is a physical change because physical change means change in which no new substance is formed. so when a mango is ripen there is no new substance formed thus it is a physical change
A physical change is best defined as?
a process that does not change the chemical composition of a substance. A change in a substance with no new substances being formed
Why is a change in the volume of a substance a physical change?
It's because no new substance is formed. It's the same substance just bigger or smaller.
What is a physical change rather than a chemical change?
`A physical change is one in which matter is changed into another physical state without changing its chemical constitution(eg-ice melts to water,in both case substance is H2O).A chemical change is where there is a chemical change of the substance during the process(eg-CaCO3 is heated to form CO2 and CaO,here the new substance formed is unrelated chemically to parent substance.)
