It's determined by the spacing of its atoms. If they are spaced close together in a rigid formation it's a solid. Somewhat spread out and fluid in formation is a liquid. Spaced far and very active in its motion is a gas.

Physical state of substances properties and behavior at room temperature and standard atmospheric pressure?
The physical state of a substance in relation to its properties and behavior at room temperature and standard atmospheric pressure will simply be the lowest energy state for the substance. This is the state that the substance can't help but go back to, unless energy is put in to do otherwise.
What does solubility depend on?
Temperature and pressure
Which phase of a substance can exist when the pressure is less than the pressure of the triple point?
This depends on the temperature.
What does a phase diagram show for a substance?
A phase diagram shows if a substance is going to be a solid gas, or liquid at a combination of pressure and temperature. It states what phase of matter a substance is at a specific temperature.
What is the importance of critical pressure?
The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature. Some examples are shown below.
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 are the 3 factors that affect the solubility of a substance?
Solubility of a substance is affected by pressure, type of solvent, and temperature.
Physical state of substances properties and behavior at room temperature and standard atmospheric pressure?
The physical state of a substance in relation to its properties and behavior at room temperature and standard atmospheric pressure will simply be the lowest energy state for the substance. This is the state that the substance can't help but go back to, unless energy is put in to do otherwise.
Why does the density of a substance remain the same for difference amounts of the substance?
Yes, under the same physical conditions influencing volume that is true (e.g. temperature and pressure).
What does solubility depend on?
Temperature and pressure
Is the amount of pressure in a gas measured in pascals?
Yes.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
What does the state of a substance depend on?
Typically pressure and temperature determine whether a substance is gas, liquid or solid. Some substances however are not easily forced into some of the states, and that is determined by by individual molecular qualities.
What determine the state of a substance?
Temperature and pressure
The rate of evaporation is affected by?
The type of substance; the substance outside this substance, the pressure, the temperature.
What is meant by saturation temperature and saturation pressure?
The temperature and pressure of the atmosphere must be at that point or in an interval of values for the substance to be saturated. When mixing solutions, the temperature and pressure must be within a certain range for the substance to dissolve.
The amount of pressure in a gas is measured in pascals true or false?
True.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
