IS MAKING TEA A PHYSICAL CHANGE OR CHEMICAL?! (10 PTS TO ANS + BRIEF EXPLANATION)

aww man...guess i was wrong after all...apparently the ans was "toasting bread is a chemical change" on my last chem test....=/...thx..i'll give u 10 pts as soon as it allows me to

Answer 1

Physical. You are boiling water and dissolving caffeine and other good stuff from the dried leaves. There is a long shot that chemical change occurs also. This is because one does not know what the heat and hydration of boiling water does to taste ingredients of tea.

Answer 2

This is a physical change. Chemicals dissolved in the cytoplasm of the cells of the tea leaves go into solution in the hot water, thus making the tea. However, the chemicals themselves are not changed in any chemical way.

Answer 3

Physical, there is no chemical reaction:

Teabag submerged in boiling water causes the tannins in the teabag to become soluble and enter the solution.
Adding sugar is just dissolving, the solid sugar crystals become surrounded by water molecules and dissolves.
Adding the milk is just mixing two liquids, the milk proteins may denature (change in molecular shape) but again that is a physical change.

No chemical reactions ---> not chemical change.

Answer 4

Its a chemical change i know for a fact, because you are not able to change the tea back into a tea leaf so therefore its chemical just like making a cake you can't turn cake back into cake mix and a physical change is when you can change back like folding a piece of paper you change the physical look but not how its chemically compounded

Answer 5

Making a tea is a chemical change.
The components in the tea sample are different chemical combination ,also when you dissolve a "chemical" or element in water,it comes out as a different compound:an obvious example is acid in some cases.
Therefore,the original tea component is not the same in water.

Answer 6

I'm getting on this a little late, so I will give you something to blow your instructor's mind. The so called "Browning" reaction of toast is actually the Maillard reaction in which "The reaction of amino groups of amino acids, peptides or proteins with the 'glycosidic' hydroxyl group of sugars ultimately resulting in the formation of brown pigments."

Answer 7

this is a chemical change because only the tea leaves are obtained but not the milk .it is not obtained in its original form
