physical change
a change in size, shape or the state of matter is a physical change. True for A+.
A physical change is a change in a substance that does not involve a change in the substance's chemical identity. Instead, physical changes only affect the state, shape, or size of the material without altering its composition. This can include changes such as melting, freezing, boiling, or dissolving.

Yes, that is correct. A physical change is a change in a substance that does not involve changing its chemical composition. This can include changes in size, shape, or state of matter without altering the substance's fundamental makeup.
Changes in size, shape, or state refer to physical transformations that matter undergoes. Size change involves alterations in dimensions, shape change involves modifications in the form or outline, and states change refers to shifts between solid, liquid, and gas phases. These changes can occur due to various factors such as temperature, pressure, or chemical reactions.
The state of matter in which the size and shape can change is a liquid. Liquids have the ability to flow and take the shape of their container due to the particles being able to move past each other while maintaining some level of cohesion.
Change in state of matter (solid to liquid or gas). Change in shape or size. Change in color. Formation of bubbles or fizzing. Formation of a precipitate.
A liquid is the state of matter that has a definite volume but no definite shape. It takes the shape of its container.
Geometric dilation (size change, typically expansion) does not change the shape of a figure, or its center location, only the size.
A physical change involves a change in appearance, shape, or form of a substance but does not involve a change in its chemical composition. Examples include changes in state (solid, liquid, gas), size, or shape.
Baking a cake is an example of a chemical change because the ingredients undergo a chemical reaction to form a new substance with different properties, such as the cake rising due to the release of gas.
