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 postulate of the kinetic molecular theory applies to the particles of a liquid?
Which postulate of the kinetic-molecular theory applies to the particles of a liquid?
They have enough kinetic energy to easily slide by each other.
What happens when the kinetic energy of particles in a liquid increase?
The particles in a liquid have more kinetic energy than the particles in the corresponding solid. As a result, the particles in a liquid move faster in terms of
vibration, rotation, and translation
.
Which process most likely takes place when the kinetic energy of the molecules overcomes the intermolecular forces?
When boiling takes place
, the kinetic energy overcomes the intermolecular forces so molecules can escape (now in gaseous form).
What is the kinetic energy of particles in a liquid?
Liquids have
more kinetic energy than solids
. When a substance increases in temperature, heat is being added, and its particles are gaining kinetic energy. Because of their close proximity to one another, liquid and solid particles experience intermolecular forces. These forces keep particles close together.
What eventually happens if energy is continually removed from a liquid?
If energy is continually removed from a liquid,
the liquid freezes to become a solid
.
How can you increase the kinetic energy of the particles in a substance?
A rise in temperature
increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
What is the relationship between the kinetic energy of molecules and their physical state?
Answer: The kinetic energy of molecules
increases when a solid melts
. Explanation: As temperature increases the movement of molecules become faster and hence Kinetic energy increases.
In which state of matter are the particles mostly touching but arranged in a random way?
In which state of matter are the particles mostly touching but arranged in a random way? -The particles are mostly touching but have a random arrangement in
a liquid
.
Which state of matter has the least kinetic energy?
Solid
particles have the least amount of energy, and gas particles have the greatest amount of energy.
Which best explains why a crystal is incompressible?
Particles in the plasma move randomly, but particles in a solid vibrate in one place. Which best explains why a crystal is incompressible?
Its molecules remain in position without vibrating
. The molecules of a crystal behave like those of a gas.
What can dissolve other substances which factor best contributes to this property of water?
Water can dissolve other substances. Which factor best contributes to this property of water?
Water is made up of ionic bonds
. Water has weak intermolecular forces.
What factor best contributes to this property of water?
Which factor best contributes to this property of water?
Water particles are not fixed in place
. You just studied 10 terms!
What are 3 substances that are liquids at room temperature?
Key Takeaways: Liquid Elements
They are
mercury (a metal) and bromine (a halogen)
. Four other elements are liquids slightly warmer than room temperature. They are francium, cesium, gallium, and rubidium (all metals).
What is the kinetic energy of particles in solid?
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
.
Does a solid have high kinetic energy?
In a solid, particles are packed tightly together so they don’t move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid
have very low kinetic energy
.
