The liquid particles, if molecules, have bonds which hold the ATOMS together in the molecule. There are also intermolecular forces of attraction BETWEEN the molecules.

What happens to particles in a substance when its heated or cooled?
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
How do the positions and movements of particles in a liquid help to explain the shape and volume of the liquid?
The particles of a liquid move from one place to another although they are close together. Because of this, a liquid changes shape depending on the container they are put in. It does not have a fixed shape. The volume of a liquid is fixed; it can be measured.
Is bromine a solid a liquid or a gas when the arrangement of particles is far apart and random?
Bromine is a liquid at room temperature. The description of particles is of atoms in a liquid.
Can matter change into a gas to a solid?
matter can be changed from a solid to a liquid and then to a gas because a solid can melt and turn into liquid and then the liquid can evaporate and turn into a gas
Change of water from a liquid to a gas state?
boiling? At around 100 degree centigrade, the heat provides the liquid water with enough kinetic energy that the particles gain so much energy that the hydrogen bonds break and the water than changes to water vapour as the particles spread out and travel much faster.
Bonds between particles are weak in?
the bonds between particles in a liquid are very weak
In a liquid particles are held together by weak bombs bands bonds or particles?
bonds
Which of the following are interactions between particles in a liquid?
Hydrogen bonds.
What forces Between the particles in a gas are weak?
the bonds between particles in a liquid are very weak
What happens to the particles in a liquid when they are heated?
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
Why does temperature influence changes in state?
Solid---Liquid: When a solid heats up the particles in it vibrate more and eventually break bonds with each other, this lets them flow apart forming a liquid, however not all of the bonds completely break, so the particles still flow in one mass.This process is called melting.Liquid---Gas: When liquid heats up the weak bonds break and the particles become free flowing with no bonds between each other, when these particles collide they do not create bonds, they bounce off each other at different angles, causing them to rise from the liquid mass. This process is called evaporation.Gas---Liquid: As a gas cools down the particles become slower moving and have fewer collisions, however the period of contact during these collisions is much longer and they create bonds between each other. As more bonds are made the particles become heavier and fall, joining other groups of particles and bonding with them until it is one liquid mass.This process is called condensing.Liquid---Solid: When a liquid is cooled it vibrates less and less causing the bonds between the particles to become stronger thus the solid stops flowing and becomes solid. This process is called freezing.Solid---Gas (and vice-versa): This process is called sublimation. Some elements and compounds that sublimate include:Carbon dioxideIodine
Are the particles in a solid linked?
Yes, they have tiny bonds that when the substance is heated break and the substance forms a liquid.
Why does a change in state from a liquid to gas require energy?
The liquid is held together by inter particular bonds. In water these are hydrogen bonds between the individual molecules of water. If these bonds did not exist then the water would not be a liquid it would always be a gas. All solids and liquids must have bonds between the particles. To change a liquid into a gas these bonds need to be broken. This is called the latent heat of vaporisation.
Why can you not compress a liquid?
The particles in a liquid are close together. In a solid the particles are tightly packed together so you cannot compress them at all. The particles in a gas are far apart, so when they are compressed the volume of the gas reduces. The bonds in a liquid are not as close as those in a solid but they are still too close for compression.
How does liquid becomes solid?
As the particles in solids are heated, they gain more kinetic energy, resulting in the particles vibrating more. This means that the bonds between the particles are broken, or weakened, meaning that the solid loses its shape and structure and melts in to a liquid.
What can the particles of gas do that the particles of liquid can't do?
Well, they can float around far apart from each other, but the particles of liquids are still confined by invisible bonds, although they can move around a bit.
How does a liquid evaporates?
The particles inside the liquid absorb heat from their surroundings, causing them to gain enough energy to break the intermolecular bonds that attract them to other liquid molecules and become gaseous.it goes in the air.
