Is it possible to change the physical characteristics of the substance by subjecting it to extremely high pressure?

Yes, physical and sometimes even chemical characteristics can be changed by subjecting a substance to high pressure.
Physical properties like state of substance, melting and boiling point, density, solubility etc can be changed by applying pressure. A gas below its critical temperature can be liquefied by pressure without cooling any further. Gases dissolve better in solvents when pressure on the surface of solvent is more( here pressure refers to pressure exerted by that gas).
You can see a cola bottle.when we open the bottle pressure decreases and carbon dioxide bubbles out. Melting point of ice decreases and boiling point of water increases( think of use of pressure cookers) with rise in pressure.
And yes chemical reactions are also affected by change in pressure especially those involving gases. Production of Ammonia is favoured at high pressure.

Do a chemical and physical property both describe characteristics of a substance?
yes they do!
The characteristics that make one substance different from another?
Characteristics of a substance can be used to identify it. Characteristics can be either physical or chemical.Example:Hydrogen, H2Physical characteristics - a colourless, odourless diatomic gas. Density, solubility, boiling and melting point, specific gravity are all physical characteristics. A physical characteristic can be observed or measured without changing the nature of the substance.Chemical characteristics - hydrogen reacts with oxygen exothermically to produce water. 2H2 + O2 --> 2H2O. Chemical characteristics change the nature of the substance ie how they react.
What are the characteristic of physical change?
Some common characteristics of physical changes are change in texture, change in shape, and change in state. There can also be a change in temperature and a change in color, but these are also common characteristics of chemical changes. A physical change does not change the composition of the original substance.
Is blue color a chemical property or physical property?
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.
What physical and human characteristics does the middle east have?
Human Characteristics: Homes and Schools Physical Characteristics: Sahara Desert
Compare and contrast chemical and physical properties?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
What the characteristics of substance and mixture?
Mixtures: can be separated by physical means

When would substance change while not changing the characteristics?
Its physical property
Do a chemical and physical property both describe characteristics of a substance?
yes they do!
When examining the physical properties of an unknown substance characteristics is unsafe to observe?
This depends on the nature of this substance; precautions are necessary.
Does a chemical property and a physical property both describe characteristics of a substance?
yes.
What happens to the characteristics of a substance during a physical change?
The change in characteristics is entirely dependent on how you have physically changed it. However most physical changes effect shape and size.
What is the differences between chemical and physical change?
A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).
Is the physical property of a substance the same as the characteristics property?
no,because physical property is a feature that can be observed and a characteristic property are differrent types of properties<3;)
What do you considered a physical property of a substance?
Examples of physical properties: density, mass, melting point, electrical conductivity, hardness, etc.Physical properties are measurable characteristics.
