What is the transformation of a physical state of a substance into a different physical state?
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
Using the phase diagram for CO2 what phase is carbon dioxide in at -60C and 15 ATM pressure?
(Explanation): If you look at the phase diagram for CO2, and you draw a lines where the temperature and pressure meet, you will see that the point will be inside the zone that is 'solid', so it is in the solid state.
What change is melting consider because energy is gained by the substance as it changes states?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Changing phases is also a physical change.
What the triple point on a phase diagram?
The triple point of a phase diagram is the location where the solid, liquid, and gas phases meet; it is the temperature and pressure at which a given substance can assume any of the 3 usual phases of matter.
A heating curve shows?
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.
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 is a graph of the relationship between the physical state of a substance nad the temperature and pressure of a substance?
Phase diagram?
What state of matter can be used in hydraulic systems?
State? Or phase? It would be a liquid phase. But its state is unknown since the state of a substance includes its pressure, temperature AND phase. Phase is a part of a state, but a state is not a phase.
What is site structure diagram?
The name of a diagram that shows how a site is structured is called the state.
When does a substance have a definite state?
A substance has a definite, defined state at all times except when going through a phase change.
What is the change of a substance from one physical state to another?
change of state
What is the transformation of a physical state of a substance into a different physical state?
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
Melting is an example of a?
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
Is there a chemical difference between the gaseous state and liquid state of a substance?
Phase has nothing to do with chemical composition.
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
When a substance moves from one state to another what kind of change occurs?
a phase change
What is a change of substance from one state of matter to another called?
Phase change. Liquid phase to gaseous phase (evaporation) Liquid phase to solid phase (solidification, freezing) Solid phase to gaseous phase (sublimation9 Etc...
