A substance can be easily compressed on applying pressure predict its physical state?
gas
What is a graph of the relationship between the physical state of a substance nad the temperature and pressure of a substance?
Phase diagram?
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.
How is pressure affected when a gas is compressed?
When a gas is compressed, so volume is decreased, the pressure increases. P=1/V
What are the 3 factors that affect the solubility of a substance?
Solubility of a substance is affected by pressure, type of solvent, and temperature.

gas
What is the meaing of compress?
Basically, compress means to squeeze. A substance is compressed by applying pressure, thus decreasing the volume. The weight of the substance, however, is not influenced. This means that a compressed substance had a higher density than its original counterpart.
Does the density of a fluid change when it is compressed?
The density of a fluid will increase according to applied pressure. Even water can be compressed so much that it eventually turns into a metallic substance. Compressed fluids will however not remain in this state when pressure is released.
What physical effect can change the boiling of substance?
Pressure
What is the graph of a relationship between the physical state of a substance and the temperature and pressure of the substance?
Phase diagram?
What happens to a substance when the pressure goes up?
The substance will be compressed (increase in density) and if the compression is adiabatic, the temperature will go up since there is work being done on the system.

For any pure substance the boiling point and melting point will always remain?
The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
What is power press?
an apparatus or machine by which a substance is cut or shaped, an impression of a body is taken, a material is compressed, pressure is applied to a body, liquid is expressed, or a cutting tool is fed into the work by pressure
Is walking on snow a physical or chemical change?
The walking is not a change at all. The snow experiences a physical change (it gets compressed, and some crystals may melt due to the pressure).
What is a metaphor rocks?
Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form. This rock was compressed into an metamorphic by the tons and tons of pressure causing it to overheat and cause a change which can be chemical or physical.
