Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the liquid forms a solid. If the pressure above a liquid is decreased sufficiently, the liquid forms a gas.
What term best describes a 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 term describes liquid behavior under pressure?
The correct answer is incompressible . Liquids or fluids that behave under pressure are called incompressible fluids because they tend to behave through flowing movements.
What are Glycerols attractive forces?
Hydrogen bonding is the predominant force for both molecules. Glycerol has three times as many O-H groups and many more H-bonding interactions than 1-propanol, so it experiences stronger intermolecular forces and greater viscosity. (Both molecules have the same carbon-chain length, so dispersion forces are similar.)
What happens as a result of the kinetic energy of the particles in a liquid being comparable?
What happens as a result of the kinetic energy of the particles in a liquid being comparable with the intermolecular attractions between the particles? The particles move enough that they are not fixed in place, and the liquid can flow. They have enough kinetic energy to easily slide by each other.
What are the consequences of liquid pressure?
Common consequences of fluid pressure – example
1. Difficulty in breathing at high altitudes . 2. Divers often feel pain in ears as the eardrums compress due to the high pressure in sea at high depths.
Which term best describes the substances that cause oil and water?
The answer is surfactant . That is the term that best describes the substance that cause oil and water molecules in salad dressing to interact and mix is surfactant. surfactants are actually the compounds that minimize the surface tension between liquids.
What are the 5 properties of liquid?

- Milk.
- Blood.
- Urine.
- Gasoline.
- Mercury (an element)
- Bromine (an element)
- Wine.
Why is liquid incompressible?
The amount of space (volume) the liquid occupies does not change (actually the volume does change but the change is very tiny). ... Liquids are always considered to be incompressible fluids, as density changes caused by pressure and temperature are small .
Are Glycerols attractive forces stronger than water?
What does this indicate about the attractive forces of glycerol? They are stronger than those in water . Two solutions that are stored at room temperature have very similar boiling points, but one solution can be poured more easily than the other.
Which liquid has the strongest intermolecular forces?
Water has the strongest intermolecular forces (hydrogen bonds) of all the substances used.
What is the force of attraction for solids?
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place .
What happens to the surface tension of a liquid when a surfactant is added quizlet?
Surfactants reduce the surface tension of a liquid . The surface tension of water is what supported the paper clip.
What happens when a solid is dissolved into a liquid?
What happens when a solid is dissolved into a liquid? ... Solid particles become suspended in the middle of liquid particles. solid particles become evenly dispersed among liquid particles . The particles in water have less mobility than the particles in oxygen.
What are the repeating subunits that are responsible for the shape of a crystal?
Particles in the plasma move randomly, but particles in a solid vibrate in one place. The repeating subunits that are responsible for the shape of a crystal are known as what? Unit cells .
