It is a physical change because no new stuff was created. NO it is not a chemical change.
physical. the water being added simply soaks through the coffee, so there's no chemical change.
The coffee remains coffee, and the sugar is simply dissolved. Thus, it is a physical change.
When coffee is added to water, that is a physical change. The coffee does not undergo a chemical reaction, the various chemical constituents of coffee remain the same. What changes is that the coffee is dissolved in water. If the water were to evaporate, leaving the coffee behind, it would be the same as it was (not counting the loss of some volatile constituents which would also evaporate, along with the water) before it was added to water.
filtering coffee is a physical change as no new products are formed after filtering and is reversible..
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.
Adding milk to coffee is a physical change, as it does not alter the chemical composition of the milk or coffee. The molecules of milk and coffee simply mix together physically, without any new substances being formed.
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.
It is a physical change.
Grinding coffee beans is a physical change as it does not change the chemical composition of the beans.
No it is a physical change.

yes dissolving sugar in a coffee is a physical change in a chemical change a new substance will be formed, and the component of this substance will be different from the parent substance. but in the case of sugar dissolving in coffee, mixture of sugar and coffee retain their respective properties. Moreover we can also separate the constituents from that mixture.and there is no new substance is formed
