Which state of matter is most affected by the shape of it container?
Gas, then liquid, and finally solid. Gases have the weakes intramolecular forces of attraction (the forces that hold molecules of a substance together), and therefore have the most freedom to move about.
How does chromatography separate molecules?
The principle is based on equilibrium of the molecules between the mobile phase and the stationary phase. This will vary depending on the polarity of the substance, and the two phases. If the substance in more soluble in the mobile phase, it will travel further, and vice versa.
What are the correct description of the phase changes?
a phases change is when a substance goes from being a solid to liquid to gas. in solids the molecules have slowed down and are ridged. In liquids, molecules have free form movement and take the shape of their container. In gases, molecules have free form movement and move quickly, they take up all the space in their containers.
Which phases of a substance can exist whe the pressure is less than the pressure of the triple point?
All three phases.
What do phase diagrams describe for a particular substance?
Phase diagrams describe the relationship between temperature, pressure, and the phase of a substance (solid, liquid, gas). They show the conditions under which a substance exists in different phases or transitions between phases.
Which state of matter is most affected by the shape of it container?
Gas, then liquid, and finally solid. Gases have the weakes intramolecular forces of attraction (the forces that hold molecules of a substance together), and therefore have the most freedom to move about.
Vapor pressure increases over a liquid in a closed container until?
Vapor pressure increases over a liquid in a closed container until the amount of vapor molecules rejoining the liquid equals the number leaving the liquid to form vapor. This is the characteristic vapor pressure of the substance.
How many phases contains a single substance?
A single substance has one phase.
How does the motion of molecules explain the phases of matter?
Solid: Molecules are tightly packed together into a fixed shape, so the molecules only have room to vibrate in place. ex: a classroom Liquid: Molecules have room to spread out and can slide past each other and takes the shape of the container it's in. ex: a hallway Gas: Molecules have room to go wherever and don't touch each other but still takes form of it's container. ex: outside; parking lot

In which of the phases of matter do molecules have the highest amount of energy?
Molecules have the highest amount of energy in the gas phase because the molecules are moving faster and have more kinetic energy compared to the solid and liquid phases.
Which phases of a substance can exist whe the pressure is less than the pressure of the triple point?
All three phases.
What is the phases change in which a substance changes from a gas to a liquid?
Condensation
What type of mixture has one substance present and two phases present?
A heterogeneous mixture with one substance present and two phases present is a suspension. In a suspension, the particles of one substance are physically mixed in another substance but are not dissolved, resulting in two separate phases. Examples include sand in water or oil in water.
What phases of matter do molecules have the highest amount of energy?
Gas.
Which phases of matter do molecules have the highest amount of energy?
gas
