In a solid, molecules are tightly packed and have a fixed position. As the solid is heated to become a liquid, the molecules gain enough energy to overcome the attractive forces holding them in place, allowing them to move more freely. This results in an increase in disorder and a change in physical properties such as shape and volume.
What else can I help you with?
How do you call a change from liquid to solid?
The change in state would be known as freezing. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
Does intermolecular force change from solid to liquid or liquid to gas?
Yes, the intermolecular forces generally change as a substance transitions from solid to liquid to gas. In solid form, molecules are held together by strong intermolecular forces. In liquid form, these forces weaken to allow molecules to move more freely. In gas form, intermolecular forces are weakest as molecules are far apart and move independently.
What can change the solubility of a solid in a liquid?
temperature. The higher the temperature of the liquid, the more of the solid you can dissolve in it.
When does a substance change from a solid to a liquid?
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
When a solid and liquid are combined and molecules disperse?
When a solid and a liquid are combined, the solid will dissolve into the liquid if it is soluble. The molecules of the solid will distribute themselves evenly throughout the liquid, forming a homogeneous mixture. This process is known as dissolution or solvation.
When a substance changes from a solid to a liquid what occurs?
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
What happens to the molecules when there is a change in state from liquid to solid?
When a liquid changes to the solid state, the molecules slow down so that they only vibrate in place and can no longer flow like a liquid.
When the molecules in a body move with increased speed it is possible that the body will change from what to what?
As the molecules in a body move with increased speed, i.e. increasing kinetic energy, it is possible that the body will change from the solid phase to the liquid phase, or the liquid phase to the gas phase, and in some cases from the solid directly to the gas phase.
Is solid ice melting to a liquid a physical or chemical change?
Melting solid ice into liquid water is a physical change. It involves a phase change from solid to liquid without altering the chemical composition of water molecules.
When the molecules in a body move with incereased speed its possible that the body will change from a?
That could cause a change from solid to liquid, or from liquid to gas.
How do you call a change from liquid to solid?
The change in state would be known as freezing. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
What is the difference between the molecules in a hot solid and hot liquid?
The molecules in a solid vibrate in place. The molecules of a liquid are moving about.
When the molecules in a body move with increased speed is it possible that the body will change from a gas to liquid or gas to a solid or liquid to a solid or liquid to a gas?
Molecules in a solid are tightly packed together and therefore have very low average kinetic energy. However, if you add energy to the system you are increasing the random motion of molecules and the intermolecular distance within the molecules increases thereby changing the substance into a liquid state. Same is true when going from liquid to gaseous state of matter. So only the liquid to gas phase change could occur, if all other conditions remain the same.
When the molecules in a body move with increased speed its possible that the body will change from a A gas to a liquid B gas to a solid C liquid to a solid D liquid to a gas?
Only one phase change of the four is possible, that of a liquid to a gas. Increased molecular energy is related to dissociative phase changes : solid to liquid / liquid to gas.
When the molecules in a body move with a increased speed it's possible that the body will change from a?
When molecules in a body move with increased speed, they gain kinetic energy. If this increase in kinetic energy is significant enough, it can lead to a change in phase, such as from a solid to a liquid, or from a liquid to a gas. These phase changes are a result of the increased movement of molecules overcoming the intermolecular forces holding them together in a particular phase.
What happens to molecules when they change from one state of matter to another?
the denseness of the molecules change(compact=solid, really far=gas, in the middle=liquid)
When change liquid to solid?
Solids change to liquids when they are heated and the bonds between the molecules are weaked so the molecules can move around more freely
