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.
What else can I help you with?
Do a chemical and physical property both describe characteristics of a substance?
yes they do!
Characteristics that describe the appearance of a substance is known as?
Nobody knows
Why liquid or gas considered a physical prperty?
Liquid and gas are considered physical properties because they describe the state of matter of a substance. Physical properties are characteristics of a substance that can be observed or measured without changing the substance's composition, and whether a substance is in a liquid or gas state is one such observable property.
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.
Is the color of iron wire a physical property?
Yes, the color of iron wire is a physical property. Physical properties are characteristics of a substance that can be observed or measured without changing the composition of the substance, and the color of iron wire is one such observable characteristic.
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.

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!
What happens to the characteristics of a substance during a physical change?
During a physical change, the characteristics of a substance such as size, shape, and phase may change, but its chemical composition remains the same. These changes are reversible and do not result in the formation of a new substance.
Does a chemical property and a physical property both describe characteristics of a substance?
yes.
Characteristics that describe the appearance of a substance is known as?

A physical property is a quality or condition of a substance that can be?
Physical properties are characteristics of a substance that can be observed or measured without changing the substance's composition. These include properties like density, color, melting point, and conductivity.
What is a not a example of a physical properties?
Personality traits, emotions, and thoughts are not examples of physical properties. Physical properties are characteristics of a substance that can be observed or measured without changing the composition of the substance, such as color, density, or boiling point.
