When a physical change occurs, the compound stays the same. For example, if you boil water, the chemical formula still remains H2O and is a physical change. However, if you were to change the chemical formula, it would be a chemical change. If H2O were split into H2 and O2 gas, it would be a chemical change.

Matter has what two qualities?
Every form of matter has chemical properties and physical properties. Physical properties are those that can be touched and sensed. Chemical properties involve how the matter reacts with other matter and under different conditions.
Is formation of gas a chemical or physical change?
Physical, because the gas is still the same gas, just under pressure Some gasses may undergo spontaneous chemical reactions under very high heat and/or pressure. For example ozone under high pressure will fairly rapidly decay into oxygen gas.
Substance that cannot be changed into a simpler substance under normal laboratory conditions?
Substance that cannot be changed into a simpler substance under normal laboratory conditions are elements. A physical blend of two or more substances that are not chemically combined is a mixture.
What are the physical and chemical properties of acid rain?
This is a chemical change.
What are chemical changes of helium?
helium has no physical or chemical change helium has no physical or chemical change
When matter under goes physical change does the composition of the matter change?
No it doesn't
When ice melts it under goes a change?
When ice melts, it is changing its state of matter, and is therefore a physical change.
What matter undergoes a chemical change the composition of the matter?
wow, did you copy this offf of a science worksheet? lol and it is "it changes" and when it goes under physical change "it remains the same"
When matter undergoes a chemical change the composition of the matter what?
wow, did you copy this offf of a science worksheet? lol and it is "it changes" and when it goes under physical change "it remains the same"
Is breaking pencil a chemical change?
Sharpening a pencil is a physical change, because there is no change to the chemical makeup of the pencil when sharpening it. It is simply chunks of wood being sliced off to reveal more of the lead.It is a physical change.
Gas under pressure physical or chemical change?
Physical change.
Under extraordinary conditions matter can be changed into?
ENERGY
Does gravity change if you're under something?
gravitation is a force of attraction that acts between and on all physical objects with matter so no it doesn't
Is it possible for some matter to change under some circumstances and not be called as mixture?
Yes, there are countless ways of changing matter, and perhaps you should be more specific to what type of change e.g. physical or chemical. If you mean a simple physical change then for example altering the shape of the matter is a way of changing it, and so is altering the size or mass. In chemical changes it is also possible to change matter without it becoming a mixture there are many ways of doing it so as to change the matter and create a compound or compounds, or to change it by creating separate elements not mixed.
Five physical properties of matter?
The physical properties of matter are properties that can be observed without causing any change in the matter under observation. Pick any five of the following 17 physical properties of matter:MassWeightHeightLengthDepthVolumeColorOdorLusterHardnessMelting PointFreezing PointBoiling PointDensityMalleabilityDuctilityConductivityNote that some of these properties, like melting/freezing/boiling point, only apply to molecular matter, as subatomic particles wouldn't have these properties.
Does ripening of papaya under a physical change or chemical change?
yes it is a physical change because physical change means change in which no new substance is formed. so when a mango is ripen there is no new substance formed thus it is a physical change
What energy is Under extraordinary conditions matter can be changed into?
the answer to this question is theory theory
