The formation of rust is a chemical change because the steel (iron) in the door has reacted with oxygen in the air to form a new substance called rust, which has properties different from the iron and the oxygen that reacted.

When you had dissolve a candy in your mouth is that going to be a chemical change or a physical change?
Physical, because it's changing state.
When you add soda ash to fabric is it a physical or chemical change?
both. the clothes becomes wet which is a physical change and the chemicals in the soda going through the fabric of your clothes is a chemical change.
Is steam turning to water a chemical or physical change?
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
Is ice going from a solid to a liquid to a gas a physical change?
Both transitions, from solid to liquid and liquid to gas are purely Physical Changes. There is nothing Chemical happening.
IF solid dry ice slowly disappears completely is this a physical or chemical change?
The "disappearance" of dry ice is a physical change. What you refer to as disappearance is actually sublimation where the solid CO2 turns to a gas without going through the liquid phase. Dry is is solid CO2 and when it disappears it becomes gaseous CO2, so it is a physical change.

Is hail a physical change or chemical change?
The formation of hail is a physical change as it merely involves water going from a liquid state to a solid state.
Is bread becoming mouldy physical or chemical change?
Bread has the right environment for mould spores to grow. It is warm (if kept out of the fridge), has a moisture content & the surface is textured perfectly for mould spores to take. Therefore it is a perfect host for their growth. As the mould spores grow, they consume the moisture in the bread and they spread into larger moulds as they consume more water. So in response to it being a chemical or physical change, there is something of both processes occurring. As the mould grows there are enzymes being produced by the mould which affect the bread and change its chemical nature, also the physical change is obvious as the bread shrivels due to dehydration. Also the colour and texture constitute a physical change. Hope this helps
How is sour milk a chemical change?
milk going sour is a chemical change because it can't be reversed. Most physical changes can be reversed for example snow melting is a physical change because it can freeze again.
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.
Is dissolving a drink mix in water a physical or chemical change?
