Is heat produced when two liquids are mixed a physical change?
No and yes. If the two liquids do not react chemically then its a physical change, called the enthalpy of mixing, heat of mixing, which can be exothermic or endothermic. If the two liquids react then the heat produced would be chemical.
Is a change of liquid to liquid a chemical change or physical change?
A change from one liquid to another is typically considered a physical change rather than a chemical change. This is because the chemical composition of the substances involved remains the same during the transition.
When you mix 2 liquids and it is warm to touch is it a chemical or physical change?
Can be both or either. 1. When mixed, without chemical reaction, liquids can take or release heat; it is a physical phenomenon. 2. But mixed liquids can react and this chemical reaction can also release heat.
Is pouring three liquids into a single container form distinct layers an examples of a chemical change?
No. It is a physical change. The layers occur because the three liquids have different densities. There is no chemical change taking place.
Is separation of 2 liquids by distillation a physical change?
Yes, separation of two liquids by distillation is a physical change. It involves the process of heating a mixture of liquids to vaporize one of the components, and then condensing the vapor back into a liquid form. This process does not involve any chemical reactions or changes in the chemical composition of the substances.
Is stapling an envelope a physical change or chemical?
A physical change
How can you tell the difference between Physical change and chemical change?
A there are physical changes but, if you know the 4 chemical changes, anything else is a physical change.OxidationBurningHeat changeBubbling (not boiling)
Is it a chemical change when 2 liquids form a solid?
No because water condense on the side of a cold glass and then evaporate again. Further answer Really, if a gas becomes a liquid it's a physical change because the gas has changed its phase from gas to liquid. It's not related to water particularly.
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
Is peeling an apple a physical or chemical change?
it is a chemical change
Is crushing charcoal into powder a physical or chemical change?
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
Is acidity physical change or chemical change?
An acid is a chemical compound, not a physical or chemical change.
