What are 3 phase changes of exothermic?
Solid to liquid (melting): This phase change requires energy to break the intermolecular forces holding the solid together, resulting in an endothermic process. Liquid to gas (vaporization): This phase change requires energy to overcome the intermolecular forces between liquid molecules, also an endothermic process. Gas to liquid (condensation): This phase change releases energy as gas molecules lose kinetic energy, forming stronger intermolecular forces in the liquid phase, and is an exothermic process.
Which change of phase represents fusion?
The change of phase that represents fusion is when a substance transitions from a solid state to a liquid state. This process requires energy input to overcome the intermolecular forces holding the particles together in a solid structure.
What is the relationship between the strength of intermolecular forces and phase change and density?
Stronger intermolecular forces generally lead to higher melting and boiling points, which are phase changes from solid to liquid and liquid to gas, respectively. Higher intermolecular forces also tend to result in higher densities due to molecules being more tightly packed together in the solid or liquid state.
What is the correct order of states from least to greatest intermolecular forces of attraction?
The correct order is: gas < liquid < solid. This is because in the gas phase, molecules are far apart and have weak intermolecular forces, in the liquid phase, molecules are closer together with moderate intermolecular forces, and in the solid phase, molecules are tightly packed with strong intermolecular forces.
What happens if intermolecular force increase?
If intermolecular forces increase, the attractions between molecules will strengthen. This can lead to molecules forming more stable structures, such as a solid from a liquid, or a liquid from a gas. It can also result in higher boiling and melting points for substances.
What force has to be overcome in order to change a solid into a liquid?
The force that has to be overcome is the intermolecular forces holding the solid particles in place. As heat is applied, these forces weaken, allowing the particles to move more freely and change from a solid to a liquid state.
Is the force of attraction stronger in the molecules of a solid or liquid?
The force of attraction is generally stronger in the molecules of a solid compared to a liquid. In a solid, the molecules are closely packed and have limited movement, allowing for stronger intermolecular forces to hold them together. In a liquid, the molecules have more freedom to move, resulting in weaker intermolecular forces.
What intermolecular forces must be overcome in order to change the crisco from a solid to a liquid?

What happens to heat during a change of starte?
During a change of state, such as melting or boiling, heat is either absorbed or released. When a substance changes from a solid to a liquid or from a liquid to a gas, heat is absorbed to break the intermolecular forces holding the molecules together. Conversely, when a substance changes from a gas to a liquid or from a liquid to a solid, heat is released as the intermolecular forces are strengthened.
What energy is required to change a solid to a liquid at the melting point.Heat of?
The energy required to change a solid to a liquid at the melting point is known as the heat of fusion or melting. This energy is used to break the intermolecular forces holding the solid together and transition it into a liquid state.
When 2 molecules of a solid are kept some distance apart and the force between them is measured solid is then melted to form a liquid. Two molecules are now kept the same distance apart and the force?
The force between the molecules in the liquid state will be weaker compared to the solid state. This is because the intermolecular forces holding the molecules together in a liquid are generally weaker than those in a solid.
Which change of phase represents fusion?
The change of phase that represents fusion is when a substance transitions from a solid state to a liquid state. This process requires energy input to overcome the intermolecular forces holding the particles together in a solid structure.
To change from solid to liquid?
To change from solid to liquid, a substance needs to absorb heat energy to weaken the intermolecular forces holding its particles together. This process is known as melting or fusion. The temperature at which this change occurs is called the melting point.
What do we call the amount of energy required to change from a liquid to a solid?
The amount of energy required to change from a liquid to a solid is called the heat of fusion. This energy is needed to disrupt the intermolecular forces holding the particles in a liquid state and rearrange them into a solid structure. It is also known as the latent heat of fusion.
What kind of change is involved when you change solid water into liquid water?
Changing solid water (ice) into liquid water involves a physical change known as melting. This process requires the addition of energy to break the intermolecular bonds holding the ice molecules together, allowing them to move more freely and form a liquid state.
What happens when you boil a solid?
When you boil a solid, it undergoes a phase change from solid to liquid as it reaches its melting point. The heat causes the solid to gain enough energy to break the intermolecular forces holding its particles together.
