Is it true or false that particles in a liquid don't have enough kinetic energy to overcome the attractive forces between them and vaporize?
It is true
What happens when water reaches a boil?
The thermal energy from heat causes the particles of the liquid to vibrate more (increasing their kinetic energy), then the vibrating particles get enough kinetic energy and are vibrating enough to allow then to break any sort of bonds (most likely ionic) that they have with surrounding particles and, as they become less dense, the liquid evaporate and becomes a gas.
What is Planetary Collision Theory?
The Collision Theory states that the rate of molecules colliding with sufficient kinetic energy successfully is proportional to the collision frequency multiplied by the fraction of collisions. The assumptions are that the molecules are spheres and traveling in straight lines.
What happens when heat energy is taken away fron molecules?
As the heat is removed, the kinetic energy of the particles decreases and they start moving very slowly. Quick reminder: kinetic energy is the energy associated with a particle's motion. The faster a particle moves, the larger its kinetic energy is.When enough energy has been removed from the system and the particles are in super slow motion, bonds begin to form between the molecules. These bonds act like glue and freeze the molecules into place.
How are chemical bonds broke?
The bonded particles are constantly vibrating and as they are given more energy (such as by heating them) they convert that energy into kinetic energy meaning that they vibrate more until they vibrate fast enough to break the forces holding them together.
Increasing the temperature of the system increases the in the system making it more likely that two particles will collide with thereby increasing the?
average kinetic energy, enough energy, reaction rate
What causes liquid to freeze kinetic energy?
In terms of energy, a liquid will freeze when enough heat energy is removed from it. This will reduce the average kinetic energy of the particles (atoms or molecules).
What happens to substance during changed between liquid and gas?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
What happens to substance during changes between gas to liquid?
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
In liquid some of the particles have enough kinetic energy to escape from the surface.what is the process called?
The answer is conduction
Decreasing the concentration of the reactants decreases the between particles thereby decreasing the probability that two particles will collide with and with?
rate of collisions, the right orientation, enough energy
Is it true or false that particles in a liquid don't have enough kinetic energy to overcome the attractive forces between them and vaporize?
It is true
What means thershold energy?
Threshold energy is the energy level where some chemical/physical action happens. For instance water boils at 100 deg C the water molecule attains enough (kinetic) energy it can escape from the rest of the pull of the water molecules. It can be used other context as well e.g. there enough electrostatic energy build up in the clouds, a lightning occur. This is the threshold energy.
What happens when fast moving molecules touch?
If they collide hard enough, and have the right orientation, a reaction can take place. This is called collision theory, and it's a big part of kinetic molecular theory.
What happens to particles when it turns to gas?
States of matter are determined by the amount of Kinetic Energy they have. When a gas becomes a liquid, it loses energy, and the particles slow down enough to affect each other. This is why liquids have a volume.
What happens when water reaches a boil?
The thermal energy from heat causes the particles of the liquid to vibrate more (increasing their kinetic energy), then the vibrating particles get enough kinetic energy and are vibrating enough to allow then to break any sort of bonds (most likely ionic) that they have with surrounding particles and, as they become less dense, the liquid evaporate and becomes a gas.
Particle moving so fast they have overcome attraction between them move independently and collide frequently?
This would mean that the particles have gained enough energy to become a gas.
