Is toasting a marshmallow a chemical change or a physical change?
When marshmallows are roasted, a chemical change happens. When you toast marshmallows, the heat causes a chemical reaction producing water molecules, which then evaporate, leaving carbon behind (the blackened part of the roasted marshmallow).
Is charring a marshmallow a physical change?
Heating the marshmallow over the fire can make the sugar caramelize, a chemical reaction that produces the brown color and toasted flavor.
Is Hammering a physical change?
Yes,hammering is a physical change since it does not change the chemical composition of a substance.
Is nail rusting a physical or chemical change?

Is cracking an egg physical or chemical?
physical changes
cracking an egg are examples of irreversible physical changes.
Is cracking an egg a physical or chemical change?
cracking an egg are examples of irreversible physical changes.
What are some characteristics of a physical change?
A physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.
Why cracking an egg is physical change?
Cracking of an egg is a physical change since the egg and the stuff inside does not change but the shape or appearance of the shell changes.
Is frying eggs a physical change?
Cooking the egg is an example of a chemical change.
Why did the luster of a marshmallow change?
Because the luster of the marshmallow changed and luster is a physical property the marshmallow underwent a physical change. 6.
Why do marshmallows expand in a no pressure environment?
Marshmallows are made of atoms too, of course. Marshmallows want to expand when they are in a no pressure environment because of a property of matter call entropy. Entropy means that when atoms are in empty space, the atoms want to move apart from each other and spread out to fill all the available space, if they can.
Why did my Marshmallow dissolve after I poured gasoline on it?
After the gasoline I used muriatic acid, which is commonly used to clean pools. After 6:56:9 seconds of soaking the marshmallow it dissolved. I concluded that a chemical change did occur because the marshmallow reacted with the chemicals.
What happens when you put Hairspray on a marshmallow?
1. With the White Rain Extra Hold hairspray my original idea was the marshmallow would disintegrate but the only change that I noticed was a change in the texture of the marshmallow (it became very slimy) and the hairspray changed a murky white color. I concluded that the hairspray did not chemical change the marshmallow. 2.
