These are phase changes - All the energy that is added at this time is used to change the phase of the substance.

What happen to the ices molecules during this phase change?

The ice (solid) become water (liquid); the distances between molecules are decreased during the change of phase, also the attraction forces.


What happens to snow molecules during phase change?

During a phase change from solid snow to liquid water, the snow molecules absorb heat energy and gain enough kinetic energy to break their bonds and transition into liquid form. This process is called melting.


Where do molecules go when ice melts?

The melting of ice is a change of phase, from solid to liquid, a physical processus. The molecules of water (H2O) remain unchanged during the change of phase.


When does a substance donot change its temperature even if it is heated?

During a phase change, a substance will remain at a constant temperature while it is being heated. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.


Is the amount of water the same after the solid ice change phase to its initial form as an ice water?

A phase change does NOT chance the total number of molecules. There will be some evaporation and sublimation too. During the time that ice melts there will some molecules that sublimate to water vapor and also some water molecules evaporate to vapor. But the total mass and number of molecules will not change.

When does the energy of water increase?

The energy of water can increase if it is heated up, if it is placed under more pressure, if it changes phase, or if it flows faster. In phase change, increase of water's energy happens from: solid phase to liquid phase (melting), from solid phase to vapor phase (sublimation), and from liquid phase to vapor phase (evaporation). Increase in altitude also increases its potential energy.


When water is heated the temp reaches a constant value and forms a plateau on the graph what does the plateau indicate?

It indicates that the temperature does not change during the phase change from liquid to gas until the change is complete. During the phase change, the heat energy added to the water goes into breaking hydrogen bonds between water molecules, so it does not cause an increase in temperature during that time.


What happens during a phase change as heat is added to a water sample?

As heat is added to a water sample during a phase change, all of that heat goes into changing the phase, say from solid ice, to liquid water, and as a consequence, the TEMPERATURE of the sampleDOES NOT CHANGE.


What happens to temperature after a phase change?

During a phase change, the temperature remains constant even though heat is being added to the system. This is because the energy is being used to break intermolecular forces rather than increase the temperature of the substance. Once the phase change is complete, the temperature will start to rise again.

What type of change occur when water changes from a solid to a liquid?

its a phase change


What happens to snow molecules during phase change?

During a phase change from solid snow to liquid water, the snow molecules absorb heat energy and gain enough kinetic energy to break their bonds and transition into liquid form. This process is called melting.


Is energy required for each phase change?

Yes, energy is required for each phase change. During a phase change, such as melting, vaporization, or sublimation, energy is either absorbed or released in order to break or form intermolecular forces between molecules.

The melting of ice is a change of phase, from solid to liquid, a physical processus. The molecules of water (H2O) remain unchanged during the change of phase.


What is a phase change example of?

When ice melts and becomes water, that is a phase change. Same when water boils and becomes steam (a gas) that is also a phase change.

When water changes into water vapor it is called what?

When water turns into water vapor it goes through a phase change. The water uses all the energy gained not to increase heat, but turn into a gas. The name for this phase change is evaporation, or vaporization.
