Which molecules would most likely cause a liquid to have?
When molecules of a liquid are small then it becomes easy for them to flow whereas when molecules are polar then they tend to form hydrogen bonding which makes the liquid more viscous. Therefore, small and non-polar molecules would most likely cause a liquid to have the lowest viscosity.
Which term best describes a 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 happens when a solid is dissolved into a liquid solid particles float?
What happens when a solid is dissolved into a liquid? Solid particles float toward the surface layer of liquid particles. Solid particles sink down toward the bottom layer of liquid particles. The particles in water have less mobility than the particles in oxygen.
Which postulate of the kinetic molecular theory applies to particles of a liquid?
The postulate of the kinetic energy-molecular theory that applies to the particles of a liquid is that liquids have enough kinetic energy to easily slide by each other. Explanation; The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving.
What happens if energy is continually removed from a liquid?
If energy is continually removed from a liquid, then the liquid freezes to become a solid.
How are attractive forces related to the motion?
The temperature of a substance is a measure of the average kinetic energy of the particles. There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together. These attractive forces are called intermolecular forces.
Which state of matter has the weakest attractive force?
gaseous state
In which state of matter are the attractive forces between molecules the weakest?
Molecular solids have lower melting points because attractive forces are weaker.
What is the strongest state of matter?
solids
Which state of matter has the biggest intermolecular space?
Solids
What are attractive forces?
There are two kinds of attractive forces shown in this model: Coulomb forces (the attraction between ions) and Van der Waals forces (an additional attractive force between all atoms).
Which attractive force is the weakest?
London dispersion force
What are the 2 types of forces of attraction?
There are two kinds of forces, or attractions, that operate in a molecule—intramolecular and intermolecular.
What forces are attractive and repulsive?
If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. This called Coulomb’s law and was the first attempt to understand the electric force. Like the gravitational force, the Coulomb force is an inverse square law.
What is the difference between attractive and repulsive force?
Attraction is a force between two charges that are distinct or unlike. Because the nuclei are positive and the electrons are negative, the electrons are attracted to the nuclei. Chemical bonds contain forces of attraction and repulsion. Repulsive forces occur only when atoms are very close to each other.
Is gravity repulsive or attractive?
In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces.
What are examples of long range forces?
Long range force A force that does not need contact between objects to exist. One example is the gravitational force (weight).
Is gravity a long-range force?
The strong force, too, operates only on short ranges. But gravity, which theorists believe is carried by particles called gravitons traveling at the speed of light, is a long-range force.
