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.
Does a substance change mass if it changes physically?
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
How does matter physically change when it changes its phase or state?
Its motion changes speed on the molecular level
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.
How did Chillingworth change physically?
hhj
What type of matter cannot be physically or chemically separated?
A compound.
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 are the ingredients in cake that physically change during their baking process?
eggs physically change while you're mixing it together, but when you bake it it is a chemical change in all the ingredients
