Things only move from one phase to another by physical means. If energy is added (like increasing the temperature or increasing pressure) or if energy is taken away (like freezing something or decreasing pressure) you have created a physical change. =)) Hope it can help!

What type of matter do not change?
solid
How does e equals mc2 show that matter can produce energy?
A better equation would be dE=dm*c2 showing that a change in mass is equivalent to a change in energy
Why can you change the order of the addends in the commutative property?
This is possible because the order of the addends does not matter. For example, 3+8 is the same as 8+3. No matter how you list the addends, the sum will always be the same.
How does an iron ball and water differ with respect to their shape size compressibility and diffusion?
because of the change of state of matter
Does the amount of a particular matter affect its density?
The simple answer to this would be no. Density is the mass per volume of a substance so if you were to add either one of these quantities the other would have to rise by a proportional amount and the density would remain constant. However this become untrue when the amount of matter you are dealing with become on the order of a planetary mass. This much matter will produce a gravitational field which will cause pressures to result that will be enough to invoke a phase change in the portions from the center of the mass on outwards. In this case the density will change with the change in phase.
How does matter physically change when it changes its phase or state?
Its motion changes speed on the molecular level
Does a substance change mass if it changes physically?
No, a substance does not change mass when it changes physically. Physical changes, such as changes in state (solid, liquid, gas) or shape, do not affect the mass of the substance. The total mass remains the same before and after the physical change.
What are change of matter?
Changes in matter are either physical or chemical. Matter changes physically when it liquefies, evaporates, freezes, etc., and chemically when it combines with other types of matter in chemical compounds.
Difference between a pysical change and a chemical change?
Chemical change changes the electrons of matter, a physical change does not. Water is water as ice, water and steam, this is a change of state but physically there is no change of water it is a change of the energy content of water.
Should matter can be changed physically?
no
How can matter be changed?
Physically or chemically.
How can hypnosis cure tuberculosis?
Hypnosis is not magic, it works on the mind. No matter how hard we all want to believe, you cannot physically change your body with your mind.
Is Matter is still the same even though it has changed state?
If you change something physically it may look, act or feel different, but it is still the same thing.
Can matter change physically and chemically?
Yes, matter can undergo physical and chemical changes. Physical changes involve a change in the form or state of matter without altering its composition, such as melting ice. Chemical changes, on the other hand, involve a reorganization of the atoms and molecules in matter, resulting in the formation of new substances with different chemical properties, such as rusting of iron.
How did Chillingworth change physically?
hhj
When does physical chang happen?
a physical change happens when something is changed physically, for example, snapping a twig or popping a balloon is physical change, but actions like burning wood or cooking an egg are not physical.
What type of matter cannot be physically or chemically separated?
A compound.
