Deleted a wrong answer-someone said "physical." It is actually a chemical reaction because it relies on the chemical properties of water and of the substances in the tea leaf. These substances-tannins, caffeine, and many others-dissolve in the hot water. The heat accelerates the reaction, but it is not a physical change. (Try steeping a tea bag in cold water-eventually you will get tea, although it will taste a bit different, probably because heat affects the dissolution of the various substances at different rates.)
a chemical reaction transforms a substance into another. in this case, the melting ice would only add more water to your tea, which is already composed primarily of water, infused with tea (leaves). ice melting is only changes the state of the substance--the substance itself does not change!
Icy Hot is a physical reaction. When applied to the skin, it produces a sensation of heat or cold by irritating nerve endings, rather than undergoing a chemical reaction.
When a cup of hot tea cools down, it is a physical change, not a chemical change. The molecules in the tea are simply rearranging as the temperature drops, but the chemical composition of the tea remains the same.
Adding lemon to tea is a physical change because no new substances are formed. The lemon flavor simply interacts with the tea molecules in a physical way.
Luster is a physical property, not a chemical reaction. It refers to how light is reflected off the surface of a material, giving it a shiny appearance. It is based on the arrangement of atoms in the material and not on any chemical changes.
its a physical reaction, called condensation
No, dissolving sugar in a cup of tea is a physical change, not a chemical reaction. The sugar molecules are simply mixing with the tea molecules to form a homogeneous solution. Chemical reactions involve the breaking and forming of bonds between atoms.

a physical reaction for the chemical structure is not changing.
The cloudiness in tea when lemon is added is due to the reaction between the tannins in the tea and the citric acid in the lemon juice. This reaction causes the proteins in the tea to precipitate out of solution, resulting in the cloudiness. It is a physical change because the appearance of the tea is altered, but the chemical composition of the substances remains the same.
It is a chemical change because Sucrose (sugar) when dissolved in water is converted into Glucose and Fructose, and can not be collected back from tea or water.
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
chemical
It's a chemical reaction
It is a physical property not a reaction
