What else can I help you with?
When a solid substance is placed in water or another liquid particles of the substance break awayand move into a liquid what is this called?
This process is called dissolution, where the solid particles break down and disperse into the liquid. This occurs when the attractive forces between the liquid molecules and the solid particles are greater than the forces holding the solid together.
What happens to the particles when a liquid becomes a soild?
The particles vibrate more until the particles break away and become more spread out. This is when they become a liquid.
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.
How could particles of a liquid end up as a particles of gas?
Usually by adding heat and/or reducing pressure.
When the particles of a solid gain enough kinetic energy to break their ordered arrangement and slip past one another what happens to the solid?
When the particles of a solid gain enough kinetic energy to break their ordered arrangement and slip past one another, the solid undergoes a phase change from solid to liquid. This process is known as melting.
Motion of particles when it finishes melting?
When a substance finishes melting, the particles have gained enough kinetic energy to break free from their fixed positions in the solid structure and move more freely as a liquid. The particles will continue to move and flow past one another in a random pattern, which is characteristic of a liquid state.
Is it true that at its boiling temperature the particles of a liquid are moving so slowly that they begin to form regular patterns?
No, at the boiling point of a liquid, the particles are moving rapidly enough to overcome the forces that hold them together in a liquid state. This allows the particles to break free from one another and escape as a gas. Regular patterns in particles are more commonly associated with solid states at lower temperatures.
Which are the first particles to evaporate from a liquid?
The particles with the highest kinetic energy are the first to evaporate from a liquid. These particles are usually found near the surface of the liquid where they can break free from intermolecular forces and escape into the air. This process is known as evaporation.
How do particles change during a change of state?
During a change of state, such as melting or boiling, the particles in a substance rearrange their positions and gain or lose energy to move from one state to another. For example, in melting, solid particles gain enough energy to break their fixed positions and move more freely, turning into a liquid. Conversely, in boiling, liquid particles gain enough energy to break free from each other and turn into a gas.
What do the particles need to do for boiling to occur?
For boiling to occur, particles in a liquid need to gain enough kinetic energy to overcome the attractive forces holding them together. This causes the liquid to transition into vapor phase as the particles break free from the liquid's surface.
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.
What do particles do in evaporation?
In evaporation, particles of a liquid gain enough energy to escape into the air as vapor. This process occurs at the surface of the liquid where particles with higher kinetic energy break free and become part of the gas phase.
