One physical change is when you bite and tear your food into smaller pieces
One horizontal cut, one vertical cut (north-south), one vertical cut (east-west). That will get you 8 pieces.
vertical expansion A+
2 horizontal cuts and 3 vertical cuts OR 3 horizontal cuts and 2 vertical cuts
the stiles are vertical and the rails are horizontal, in other words, the stiles are the side pieces and the rails are the cross pieces
If a cube of jello is cut into two pieces the density of the pieces do not change.
Sublimation which is the change in state from a solid directly to a gas without passing through the liquid state.
vertical expansion A+
When you tear a piece of paper, a physical change occurs as the paper is physically broken apart into smaller pieces. This change does not alter the chemical composition of the paper, so it remains the same substance before and after tearing.
3face = 8 pieces, 2face = 12 pieces, 1face = 6 pieces, 0face = 1 piece
Weathering is a slow change that occurs over time as a result of exposure to the elements such as wind, water, and temperature. It breaks down rocks and other materials into smaller pieces through various processes such as physical or chemical weathering.
Vertical rods are long, slender pieces of metal or other material that are positioned in a vertical orientation. They are often used for structural support, reinforcement, or as part of machinery or equipment. In construction, vertical rods are commonly used in reinforced concrete to provide strength and stability to structures.
