Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. The attractive intermolecular forces between particles that tend to draw the particles together.

What factors help determine the physical properties of liquids quizlet?
What factors determine the physical properties of a liquid? The interplay between the disruptive motions of particles in a liquid and the attractions among the particles determines the physical properties of liquids.
What are 5 physical properties of a liquid?
We hope that these cursory explanations of the nature of liquid characteristics provide a rudimentary understanding of and a curiosity about these five liquid properties: surface tension, consistency, viscosity, contact angle and density.
What are properties of liquids?
The most obvious physical properties of a liquid are its retention of volume and its conformation to the shape of its container. When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel.
What determines the physical state of a solution?
The solvent is the substance which typically determines the physical state of the solution (solid, liquid or gas). The solute is the substance which is dissolved by the solvent.
Why do liquids have a definite volume and what determines their physical properties?
Liquids. If the particles of a substance have enough energy to partially overcome intermolecular interactions, then the particles can move about each other while remaining in contact. This describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume.
What conditions must be met for a liquid to boil?
A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil.
Why does the boiling point of a liquid vary with atmospheric pressure?
The boiling point of a liquid is directly affected by atmospheric pressure. This is the pressure exerted by the weight of the air molecules above the liquid. In an open system this is called atmospheric pressure. The greater the pressure, the more energy required for liquids to boil, and the higher the boiling point.
What are the 10 properties of liquid?
- Capillary Action.
- Cohesive and Adhesive Forces.
- Contact Angles.
- Surface Tension.
- Unusual Properties of Water.
- Vapor Pressure.
- Viscosity Viscosity is another type of bulk property defined as a liquid’s resistance to flow.
- Wetting Agents.
What is the physical state of liquid?
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
Which of the following is a property of a liquid?
Liquids have no fixed shape but have a fixed volume. They take up the shape of the container in which they are kept. Hence do not have distinct boundaries.
What are four physical properties of a liquid?
- Liquids are almost incompressible. In liquids molecules are pretty close to each other.
- Liquids have fixed volume but no fixed shape.
- Liquids flow from higher to lower level.
- Liquids have their boiling points above room temperature, under normal conditions.
Which defines a liquid?
A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. The term liquid is also used in reference to the state, or condition, of matter having this property.
What properties are used to describe liquids and gases?
Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded. They move around but stay close together. Gases – no definite volume or shape.
What factors affect the properties of a solution?
Factors affecting the formation of the solution: Proportion of the solute & the solvent: Solute should be in less quantity and solvent should be more in quantity to dissolve the solute. Particle size of the solute: Small size of particles of the solute dissolve faster.
What are the three factors that determine whether a substance will be a solid a liquid or a gas?
- Kinetic energy of atoms, ions or molecules of substance.
- Intermolecular force of attraction.
- Intermolecular spaces between atoms.
What determines the properties of a solution quizlet?
The state of matter of the solution will take the state of matter of the SOLVENT. This is because the solvent is in a larger amount and ultimately dictates the form of the solution. a solution that contains less solute than the solvent has the capacity to dissolve AT A SPECIFIC TEMPERATURE.
Why do liquids have different properties?
Liquids take the shape of the container in which it is kept and also occupies space. The liquids have low inter-molecular force in between the molecules as compared to solids but higher than that of gases. The inter-molecular space between the molecules of liquid allows them to flow.
What are the physical properties of matter?
Physical properties, such as mass, volume, density, and color, can be observed without changing the identity of the matter. We can further categorize the physical properties of matter as either intensive or extensive. Intensive properties do not depend on the amount of the substance present.
What two factors affect the boiling point of water?
Answer and Explanation: The two factors that affect the boiling point of water are the pressure the water is under and whether or not there are impurities or particles in the water. The higher the pressure on the water, the higher its boiling point.
What do all liquids have in common?
Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility.
Which properties of a liquid are seen in the distillation method?
Use your brain power: Which properties of a liquid are seen in the distillation method? Solution : The liquid has a particular temperature for boiling point and also a particular temperature for condensation.
Why does water boil faster at high altitudes?
At high altitudes, the pressure cooker is an essential kitchen tool. By cooking under pressure you are in effect increasing the atmospheric pressure and therefore, increasing the boiling temperature of water.
Why does water boil faster at lower pressure?
The boiling point of a liquid is defined as the temperature at which the vapor pressure of the liquid is equal to the external pressure. When the pressure above a liquid is reduced, the vapor pressure needed to induce boiling is also reduced, and the boiling point of the liquid decreases.
Why boiling point of water is lower at higher altitude?
At a higher elevation, the lower atmospheric pressure means heated water reaches its boiling point more quickly—i.e., at a lower temperature. Water at sea level boils at 212 degrees Fahrenheit; at 5,000 feet above sea level, the boiling point is 203 degrees F.
