What are he cHANGES THAT PLACE INSIDE THE MATTER DURING THE CHANGE OF STATE?

The thing that changes during a change of state is the intermolecular forces are disrupted. The temperature will not change because all of the energy is going into disrupting or organizing the intermolecular forces.


Why does temperature stay constant during a phase of change?

Because energy is being used to overcome intermolecular forces.


What are the three factors that are affected during phase change in matter?

Three factors affected during a phase change would be temperature, pressure and intermolecular forces/internal energy.


Why does temperature no change during energy phase change?

During a phase change, the heat transferred to a substance is used to break intermolecular forces (latent heat), and thus the temperature of the substance does not change. The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.


Why does the temperature of any substance remain constant during the change of a state?

because energy is required to break the intermolecular forces in the molecule

How are intermolecular forces different from forces that bind atoms together into molecules?

1. Intermolecular forces are the forces between molecules, while chemical bonds are the forces within molecules. 2. Chemical bonds combine atoms into molecules, thus forming chemical substances, while intermolecular forces bind molecules together. 3. Chemical bonding involves the sharing or transferring of electrons, while intermolecular forces do not change the electron stucture of atoms. 4. Intermolecular forces hold objects together, while chemical bonds hold molecules together.
