Is food dye a physical or chemical change?
Physical, the water is still water and the food coloring is still food coloring you just mixed them together in one space. If you waited long enough the food coloring and water would settle back out so you had just water and food coloring.
What is an example of both a chemical and physical change?
A physical change is melting a crayon because it changes in shape but it does not change the chemical composition. A chemical change is making a cake because once you have added the ingredients you cant remove them and it becomes a new substance.
What is the example of physical change and chemical change?
Physical ChangesChange of state (such as from solid to liquid or from gas to liquid) Specific examples of state change include water freezing, alcohol evaporating and dry ice (solid carbon dioxide) sublimingAbsorption of water into a towelCrumpling a piece of paperPulling copper into a thin wire - a change of shape, but not a change of compositionCutting a material such as woodTearing a piece of tin foilBreaking glassDeflating a basketballMixing different solids (such as solid sulfur and iron filings)Inflating a volleyballCloud forming in the skyChemical changesBurning a log of woodMixing an acid with a base, producing water and a salt.Photosynthesis - a process in which carbon dioxide and water are changed into sugars by plants.Cracking heavy hydrocarbons to create lighter hydrocarbons (part of the process of refining oil).Cooking examples: popcorn, cake, pancakes, and eggsOxidation examples: rust or tarnishingCombustionMixing chemicalsRotting of fruitCooking riceExplosion of fireworksTarnishing silverLighting a matchChewing/digesting foodRusting nailBurning gas in a stoveOxidizing food for energyRoasting a marshmallowAdding food coloring to icingFrying an eggBurning a magnesium stripThe following can indicate that a chemical change took place, although this evidence is not conclusive:Change of color (for example, silver to reddish-brown when iron rusts)Change in temperature or energy, such as the production (exothermic) or loss (endothermic) of heatChange of form (for example, burning paper)Light, heat, or sound is given offFormation of gases, often appearing as bubblesFormation of precipitate (insoluble particles)The decomposition of organic matter (for example, rotting food)
What are the example of physical change and chemical change?

How do physical features affect where people settle?
Geographic conditions change the way we live. For example if you lived in India, you would have to learn how to fish and protect yourselves from the monsoons. If you lived in Antarctica, you would have to make clothing suitable for the cold weather.

What types of change is a change of state?
Changing between one of the states of matter. More commonly a solid to a liquid (ice melting) or a liquid to a gas (water evaporating).
Example of chemical and physical changes?
Properties such as shape, size, colorand state of a substance are called itsphysical properties. A change in whicha substance undergoes a change in itsphysical properties is called a physicalchange.when the new substance is formed then it is chemical changecutting of paper is physical changeburning of paper is chemical change .note:when the is mansion in the reaction. it is chemical changeProperties such as shape, size, colourand state of a substance are called itsphysical properties. A change in whicha substance undergoes a change in itsphysical properties is called a physicalchange. A physical change is generallyreversible. In such a change no newsubstance is formed.A change in which one or morenew substances are formed is called achemical change. A chemical changeis also called a chemical reaction.cutting of a paper is the physical change .burning of a paper is chemical change(when burning is mention in the given question it will become a chemical change)burning of a candle is both chemical change and physical change.
What kind of matter does dynamite change to after the explosion?
Dynamite and its effect on matter is fascinating to consider. At the moment of setting off dynamite (TNT) there is a chemical change within the dynamite itself. The effect of this chemical change initiates a physical change--in rock, boulders, soil as the blast hits. Physical change continues as material slams back onto other material (e.g. rock against rock) turning more large size rock to smaller rocks and dust particles. At the same time, the chemical charge which occurred in the dynamite changes physical matter of the local site's air... which then also becomes mixed with dust particles. Both the chemical changes to air and the physical changes of rock blasted into the air must settle and clear. Using dynamite is somewhat similar to an eruption of a small volcano that throws up matter into the air within a chemical and physical change to rock, soil, and surrounding air, including at higher elevation--not just at ground level.
Did the Australian government promise that no nazi would ever be allowed to settle in Australia?
No, the Australian government did not promise that no Nazi will be allowed to settle in Australia.
Allowed hunters and gatherers to settle in one spot?
The Neolithic Revolution allowed hunters and gatherers to settle in one spot due to the development of agriculture.

Why do people use physical violence to settle disagreements?
People use physical violence to settle disagreements because they have no patience, are not too smart, are not thinking clearly when trying to settle the disagreement, and have a death wish.
