A physical change is a change where the physical condition of a substance is altered, but no chemical reaction takes place. For example, the change of water (in liquid form) into ice (a solid) is a physical change, as the water has changed in physical condition.
A chemical change is a change where the chemical structure of a substance is altered. For example, burning a piece of magnesium (reacting magnesium with oxygen) produces magnesium oxide (a new substance).

∙ 11y agoPhysical changes affect the form of a substance or object but not the actual chemical composition. This type of change is more concerned with energy and states of matter. The starting and ending materials of all physical changes remain the same even if the before and after are different in appearance.
Examples of physical changes include: breaking a bottle, melting an ice cube, boiling water, and shredding paper.
Chemical changes affect the molecular composition of a substance or object (take place on the molecular level). The starting and ending materials of all chemical changes will be different.
Examples of chemical changes include: rusting (iron reacting with oxygen, or the formation of iron oxides), mixing Chlorine (Cl) and Sodium (Na) to form Sodium Chloride (aka table salt), burning wood (combustion).

∙ 14y agophysical change is when an object is changed only in position, shape, size, weight, etc. chemical change is when the actual chemical composition of an object is altered, changing it's type or how it reacts with other objects.

∙ 14y agoA physical change can be defined as something which changes the state of a substance, eg. heating water into steam is a physical change
A Chemical change is where atoms in the substance are rearranged, eg the electrolysis of water.

Is mixing water to baking soda a physical or chemical change?
It is a chemical change, some other signs of chemical changes you should look for to differentiate between physical and chemical changes are: thermal energy radiating off of the objects, the result in another object that has different properties then the first two, etc...
