During which phase change does the average distance between molecules always increase?
During the phase change from a liquid to a gas, the average distance between molecules always increases.
Why does an energy transfer not always result in a phase change?
An energy transfer does not always result in a phase change because the energy can be used to increase the temperature of a substance without causing it to change from one phase to another. Phase changes occur when a substance reaches a specific temperature and energy level that causes its molecular structure to rearrange, such as melting or boiling.
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Is a phase change an example of a physical or chemical or nuclear or a covalent change?
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
When a solid is heated it will usually change to this phase?
When a solid is heated, it will usually change to the liquid phase. This process is known as melting.
During which phase change does the average distance between molecules always increase?
During the phase change from a liquid to a gas, the average distance between molecules always increases.
Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.

In which phase change does a substance change from a solid to a gas or vapor without changing to a liquid first?
Corn, corn is always the answer.
When heat is transferred does the temperature always change?
No, when heat is transferred, the temperature doesn't always change. This is because heat transfer can result in either a change in temperature, a change in phase (such as melting or boiling), or a combination of both.
What is the phase change in a boiling point?
What is the phase change in evaporation
What must always accompany a change in state?
Energy must always accompany a change in state, whether it is in the form of heat, work, or a combination of both. This energy is necessary to either break the bonds between particles during a phase change involving an increase in energy, or to form bonds between particles during a phase change involving a decrease in energy.
How do you get a change of phase?
Change of phase is caused 99% of the time by a change in temperature or pressure.
What is it called to change states of matter?
Phase change. Liquid phase to gaseous phase (evaporation) Liquid phase to solid phase (solidification, freezing) Solid phase to gaseous phase (sublimation9 Etc...

What phase change causes water to evaporate?
This phase change is called evaporation.
