Physical but especially also chemical because the instant coffee suffer a process of solubility in water.
Mixing a teaspoon of coffee into hot water is primarily a physical reaction. The coffee granules dissolve in the water, resulting in a solution, but no new substances are formed. This process involves the physical dispersion of the coffee particles rather than a change at the molecular level that would indicate a chemical reaction.

Instant coffee is soluble, meaning it can be dissolved in water. This is why it is preferred by many for its convenience and quick preparation.
Mixing hot coffee with cold milk is a physical change because the molecules of both substances do not undergo a chemical reaction. The temperature change occurs due to heat transfer from the coffee to the milk, but the chemical composition of the coffee and milk remains the same.
Instant coffee in water is a homogeneous mixture, meaning it has a uniform composition throughout. The coffee particles are fully dissolved in water, resulting in a consistent mixture.
A teaspoon of instant coffee typically contains around 30-40 milligrams of caffeine.
One teaspoon of instant coffee typically contains around 30-40 milligrams of caffeine.

To make a delicious latte at home using instant coffee and milk, start by mixing a spoonful of instant coffee with hot water to make a strong coffee base. Froth milk using a frother or by shaking it in a jar. Pour the frothed milk over the coffee and enjoy your homemade latte!

Mixing coffee with hot water is a physical change because the individual substances (coffee and water) retain their chemical identities and only the physical state of the coffee changes, dissolving in the water. No new substances are formed.
Water and instant coffee would be considered a mixture. A mixture is a combination of two or more substances that are not chemically bonded together. Water and instant coffee retain their individual properties and can be separated through physical means such as filtration or evaporation.

The instant coffee and the water have not changed chemically or physically. It becomes a mixture, not a solution; the water is separate from the coffee powder. Therefore it is not a physical change.
No, coffee powder and instant coffee are not the same. Coffee powder is ground coffee beans, while instant coffee is a processed form of coffee that dissolves quickly in water.
No, stirring milk into hot coffee is a physical change. The milk and coffee remain the same substances they were before mixing, only their physical state has changed.
