it is a physical change because the appearance just changed.
No, it is a physical reaction because it doesn't undergo any change in chemical properties.
making lemonade is a physical change i believe
yes it is because it is not changing the substance. EDIT: yes it is what? Is it chemical or physical? You probably mean it is a physical change.
Chocolate milk is a mixture. It is not a change of any sort. The making of chocolate milk is a physical change as none of the components change their chemical identity.
A mixture cannot be separated with chemical change because a mixture is two or more substances which will retain their physical properties when combined. Mixtures are separated by physical means like filters, sifting, chromatography, centrifuge, electrophoresis and magnetic attraction depending on what the mixture is composed of.
filtering coffee is a physical change as no new products are formed after filtering and is reversible..
Filtering air to remove dust and pollen is a physical change because the process does not alter the chemical composition of the dust and pollen particles. It simply separates them from the air through physical means, such as using a filter.
physical change
No, filtering something is not a chemical change.
Filtering air to remove dust and pollen is a physical change. This is because the process does not alter the chemical composition of the air or the dust/pollen particles. Instead, it simply separates the particles based on their physical properties.
yes it is a physical change. there is no chemical change
when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
physical
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.
physical- there's no chemical change.
No, it is a physical reaction because it doesn't undergo any change in chemical properties.
Sodium chloride is a chemical compound not a change.Sand is a mixture not a change.
