Smashing a pumpkin is a physical change.
Smashing a pumpkin is a physical change because it alters the appearance and shape of the pumpkin without changing its chemical composition.
Smashing a pumpkin is a physical change because the pumpkin is being broken down into smaller pieces without altering its chemical composition. The bonds between the pumpkin's molecules remain the same, even though the shape of the pumpkin changes.
Carving pumpkin physical change or chemical change
Carving a pumpkin is a physical change because it alters the pumpkin's shape and appearance without changing its chemical composition. The process involves cutting and removing parts of the pumpkin's exterior, which affects its physical properties, such as texture and size. However, the pumpkin's internal structure and the materials it is made of remain unchanged. Thus, the transformation is purely physical.
Smashing a car is a physical change because when the car is smashed it's, still the car. You didn't use any chemiclas to change it - the changes are only in appearance. So it's still a car until you use some kind of chemical to change it.
Frost forming on a pumpkin is a physical change. This process involves the transition of water vapor in the air into ice crystals as temperatures drop, without altering the chemical composition of the water. The pumpkin itself remains chemically unchanged, although its physical state may be affected by the frost. Therefore, it is classified as a physical change.
It is a physical change.
Frost on a pumpkin is a physical change. It occurs when water vapor in the air freezes on the surface of the pumpkin, forming ice crystals. This process does not alter the chemical composition of the pumpkin itself; rather, it is a temporary condition that can change with temperature fluctuations.

The bug splattered on the windshield is a physical change because the bug's physical state changed from solid to liquid upon impact. There is no change in the chemical composition of the bug or the windshield.
Smashing a rock is a physical change because it alters the rock's appearance and size, but not its chemical composition. The pieces of the rock remain the same material and can potentially be put back together.
This process involve chemical reactions but also physical changes.
