Acharacteristic of matter that doesn’t change even with a very small or very large simple size

Remember all objects take up space and have mass. You use your sense of taste and smell to tell the difference between spinach and an orange.
Physical properties- The measurement of mass and other characteristics that can be seen without changing how that object looks are its physical properties. When you look at oranges, you know that they are oranges because of their color, shape, and smell. Mass, color, shape, volume, and density are some physical properties. The answers to the question about the present are physical properties.
Density is an important physical property. Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies.
Chemical properties- These are properties that can only be observed by changing the identity of the substance. A piece of paper burns and turns to a black substance. After the flame goes out you can no longer burn the new substance. The chemical properties have been changed.

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
