A physical change only changes the appearance of an object, it's chemical makeup is still the same. Melting ice doesn't change it to a different object, just a different state. Like if you rip a piece of paper, it's still a piece of paper. But a chemical change changes the makeup of the object. Burning is a chemical change. Once it burns it is no longer paper.
What else can I help you with?
Is bolling an egg a phyical change or chemical reaction?
Irreversible chemical change.
Is frying chicken phyical or chemical?
Frying chicken involves both physical and chemical changes. The physical change occurs as the chicken cooks and changes color and texture due to the application of heat. The chemical change happens as the proteins and sugars in the chicken undergo reactions that result in browning and flavor development.
Is water into an ice cube a phyical change or a chemical change?
physical because water is H2O and ice is H2O also
Can a chemical change be reversed by a chemical change?
It Looks like your tryhing to cheat on Science TeeHee Chemical changes cannot be reversed but phyical changes can ! I disagree. Some chemical changes can be reversed. If you boil off the water and catch it in a container when it evaporates, the water will be back. If you then look at the bottom and possibly sides of your beaker there will be only salt left behind.
What two phyical changes are involved in distillation?
In distillation, two physical changes involved are evaporation (liquid turning into vapor due to heat) and condensation (vapor turning into liquid when cooled). The process separates components based on their different boiling points.
When you bleach your hair is it a phyical or chemical?

Can matter undergo a phyical and chemical change at the same time?
Yes, matter can undergo both physical and chemical changes simultaneously. For example, when a candle burns, the wax undergoes both a physical change (melting) and a chemical change (combustion) at the same time.
Is a cigarette a phyical change?
No, all the changes smoking does to the body are chemical, nicotine is a chemical that is addictive, the smoke and other chemicals created from the smoke make your teeth yellow, stop the growth of hair and all the other nasty stuff that happens to a habitual smoker.
Why is reactivity not a phyical property?
A physical change doesn't involve chemical reactions, change of the molecule structure.The chemical reactivity is about the ability of an element or compound to realize chemical reactions.
How could you prove that table salt in water is a phyical change not a chemical change?
that is because salt is a physical matter
Is water into an ice cube a phyical change or a chemical change?
physical because water is H2O and ice is H2O also
Do a eagle fly higher then a goose?
the phyical difference between a geese and eagle
Is dissolving of sugar in water a chemical or phyical reaction?
Dissolution is usually considered a physical reaction, although weak chemical bonds between the solute and solvent may exist in the solution.
