A physical change is one in which after the rxn. or process each constituent retains it's properties.
When we mix sugar and coffee, first of all they don't mix in each other... or in other words in that mixture sugar and coffee retain their respective properties. Moreover we can also separate the constituents from that mixture.
The coffee remains coffee, and the sugar is simply dissolved. Thus, it is a physical change.
Physical
Sweating coffee with sugar is primarily a physical change. When sugar dissolves in coffee, it does not alter the chemical composition of the sugar itself; it simply disperses in the liquid. The process of sweating, or condensation, occurs when moisture from the air collects on the surface of the coffee, which also represents a physical change as it involves the transition of water vapor to liquid.
Mixing sugar in a coffee is a physical change. Mixing sugar in coffee is a physical change because it does not form a new substance, it is still sugar and coffee. If you decided to mix sugar and water to make sugar water, the water could be left to evaporate and the sugar crystals would still be there. So mixing sugar in coffee is also very easy to reverse.
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
a physical change
its as physical change as no reaction takes place. the sugar fills in the gaps between the water molecules so you cant see it un till you filter or dissolve the coffee.
It is a physical change.
filtering coffee is a physical change as no new products are formed after filtering and is reversible..
Sugar crystallizing is a physical change because it involves rearranging the molecules of the sugar without changing their chemical composition.
Grinding coffee beans is a physical change as it does not change the chemical composition of the beans.
no, powdering of sugar is a physical change as it does not forms into a new substance
