What else can I help you with?
Are melting evaporation condensation and sublimation examples of physical properties or physical changes?
Yes; sublimation is the conversion of a substance from solid directly to gas. Since no chemical change occurs, simply a different state of matter, this is a physical property.
A physical property that depends on the amount of matter in the substance is?
a physical property that depends on the amount of matter present
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
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.
What is a physical form that a substance can exist?
Solid, liquid, gas, or plasma. A substance can occur in any one these states. All matter occurs in one of these 4 states. These are the 4 states of matter.
What is a physical matter from which something is made?
an object that has only one substance.(FOR EXAMPLE)water and suger is a chemical matter because the sugar disolves into the water but it is still water and it is not a physical matter because the a physical matter changes from one state to another.
What if you mix matter with another substance?
What happens would depend on what sort of matter you are stirring in.
Is photon matter a form of energy or a form of physical substance?
Photon matter is a form of energy, not a physical substance.
What is a purely physical association of a substance?
the purely physical association of a substance is matter.
What is physical and changes in matter?
a physical is a change to a substance
What is a property of matter that doesnt change a substance into a new substance?
Physical property of matter
When a substance from any state of matter to another is called a?
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
How do chemicals differ from physical changes?
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
What is the physical form in which a substance exists?
matter
How are states of matter and physical properties the same?
States of matter and physical properties are related because physical properties are characteristics that can be used to describe the state of matter a substance is in. For example, if a substance has a fixed shape and volume, it is in a solid state of matter. The physical properties of a substance determine how it behaves in different states of matter.
What does not change when a substance changes matter?
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
Soil is a substance?
Soil is a substance; anything consisting of real physical matter is a substance.
