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.)
The color change in iced tea occurs because the ice dilutes the tea as it melts, causing the tea to become lighter in color. This is due to the ice adding water to the tea, which reduces the concentration of the tea itself.
When sugar dissolves in tea, the sucrose molecules break apart into glucose and fructose due to the water molecules in the tea. This process is a physical change, not a chemical reaction, as the chemical composition of the sugar molecules remains the same.
Heating a cup of tea is a physical change, not a chemical change. The heat causes the molecules in the tea to move faster, but the chemical composition of the tea remains the same.
It is a physical change because the sun's rays create a physical differential not chemical relates to chemical change ie: the ice tea crystals dissolve in the water. --------- Chemical change, because fading in this case is the result of a photochemical reaction.
Ice cube melting is a physical change as it involves a phase change from solid to liquid, without altering the chemical composition of the substance.
I would assume iced tea. Ice tea would suggest the primary compound being ice, so that the tea itself is composed of mainly ice. Iced tea refers to the status of being iced, or in ice. This would probably make more sense. I mean... try making tea out of ice without melting it. Hope I awnswered your question.
H2SO4W3FE5O6SO3 + nitrous oxide = Arizona ice tea

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.
No, ice tea with ice cubes is not an element. Elements are pure substances that cannot be further broken down by chemical means. Ice tea and ice cubes are both mixtures consisting of various compounds and elements.
me, chat, tea, team, miracle,......Your figure out the rest...
it's a reversible change
Physical, because you are only diluting the tea, but not creating a new substance.
its a physical reaction, called condensation
Tea... And Ice...
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.
