Two categories used to classify properties of matter are physical properties and chemical properties. Physical properties can be observed or measured without changing the composition of the substance, while chemical properties describe how a substance changes into a new substance through a chemical reaction.
Two physical properties of a bag of microwave popcorn before popping are its mass and volume, which remain constant before and after popping. Two chemical properties that change after popping are the composition of the kernels, which undergo a chemical reaction to turn into fluffy popcorn, and the release of aroma compounds due to the Maillard reaction during popping.
The dimensions: height, length, and width.
Two physical properties that can vary without changing the substance are temperature and pressure. For example, water can exist as a solid (ice), liquid, or gas (steam) at different temperatures and pressures, but it remains chemically the same H2O molecule.

A standard graham cracker is typically a rectangular sheet that can be broken into two squares along its perforated lines. Therefore, while the whole cracker is considered one piece, it can be divided into two square sections.

The graham cracker was developed in 1829 in Bound Brook, New Jersey by Presbyterian minister Rev. Sylvester Graham. Though called a cracker, it is sweet rather than salty, therefore in actuality it is a cookie not a cracker.See my answer to "Who first ate graham cracker's" if you would like more information on this topic.Who_first_ate_graham_crackers
Two categories used to classify properties of matter are physical properties, which describe the characteristics that can be observed without changing the substance's chemical composition, and chemical properties, which describe how a substance interacts with other substances to form new substances.
