Dissolving salt into water is it physical or chemical change?
This is a physical change. You can separate the salt and water by the physical process of distillation or evaporation where the water is boiled away and the salt is left behind.
How does the size of the particles effect the rate of dissoving?
Actually, it is not the size that matters, but the area of contact. we see that the dissolving of an object happens because there are collisions between the solvent and the solute. When the solute is BIG, for example, a block, the solvent can only collide with the surface of the block, but not the middle of the block. that means it will take a longer time for the solvent to dissolve the solute. When the block is pondered into a powdery state, it is easier for the solvent to dissolve the solute because of the larger area of collisions.
Is dissoving a chemical change?
Dissolving is a physical process.
Is suger dissoving in water a physical or chemical change?
Dissolving is a physical change.
Is making a cup of coffee a chemical reaction?
No, it is dissoving and/or extracting the flavourous compounds already present in tea.

What is the method for sugar dissoving into water?
Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent. The solubility of a substance fundamentally depends on the used solvent as well as on temperature and pressure. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration where adding more solute does not increase the concentration of the solution.

How does the hardness of water affect the dissoving of soap?
The soap attaches to, envelopes, the minerals in the water and so then it takes ALOT more soap to create suds, or in particular, a cleansing affect. The use of surfectants (water-softening agents) enables you to use less soap with normal tap water. While people think soft water makes it harder to wash off the soap, actually it is the opposite. The best cleaner in the world is "clean water", mineral free water, and it will rinse your clothes, dishes, skin, etc. soap free.
