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
When two clear colorless liquids are combined and the mixture turns cloudy physical or chemical change?
When two clear colorless liquids are combined and the mixture turns cloudy, it typically indicates a physical change, such as the formation of an emulsion or a precipitate. This cloudiness often results from the dispersion of one liquid in another, rather than a chemical reaction altering the substances' chemical identities. However, if a new substance is formed with different properties, it would indicate a chemical change. Overall, the context and nature of the liquids involved can clarify which type of change has occurred.
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.
