What do physical changes do?
There are many different physical changes that can take place at any given time. To know what exactly these certain physical changes mean we would need to know what the changes are.
Describe the changes that take place when a match burns Are these changes physical or chemical changes?
physical, there is nothing going on but friction, which causes heat, which causes fire.All three are physical.
When sugar is heated a thick liquid substance is formed what change takes place?
magic. maic and magnets.
What is differentiate physical change and chemical change?
A physical change is a change where the physical condition of a substance is altered, but no chemical reaction takes place. For example, the change of water (in liquid form) into ice (a solid) is a physical change, as the water has changed in physical condition. A chemical change is a change where the chemical structure of a substance is altered. For example, burning a piece of magnesium (reacting magnesium with oxygen) produces magnesium oxide (a new substance).
When sugar is heated for a short time a thick colorless liquid substance is formed What kind of change takes place?
A chemical change takes place.
Heating curve illustrates what?
When a substance is heated, a heating curve shows the changes in temperature as well as the physical state of the substance. A heating curve can chart the temperature versus the time elapsed as the changes take place.

Is water condensing a chemical change?
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.
Is putting pottery in heated place a physical or chemical change?
It is a physical change
Why is solubility a physical change?
While solubility is undergoing changes in their substances wheather it could be from a mechanical deformation, exposure to another substance, or any of a number other alterations. If the same substance remains after the change, a physical change has taken place.
What kind of changes is it chemical or physical and why?
a physical change is a phase change, such as water to ice or water vapor. a chemical change takes place on a molecular level, producing a new substance.

Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
