True. Flammability is a chemical property of matter. It is not a physical property of matter. When wood burns, it changes to ashes, carbon dioxide, water vapor, and other gases. After burning, it is no longer wood.
False. In a physical change, the makeup of matter remains the same, only the physical properties like shape, size, or state are altered. No new substances are formed during a physical change.
True. A scientist can observe and measure the color of matter to gather information about its properties or composition. This is a common technique used in various scientific disciplines such as chemistry, physics, and biology.
True. Squeezing and stretching matter can involve elastic forces, which result from the deformation of the material and its ability to return to its original shape once the force is removed. This behavior is characteristic of elastic materials such as rubber or springs.
Matter cannot be subdivided is a false statement. Matter can be broken down into smaller particles such as atoms, which are the building blocks of matter.
False. An electric motor does not transform matter. It transforms electrical energy into mechanical energy to produce motion.
false
False. A characteristic of rock is that the individual minerals lose their distinct properties when combined into a rock. The resulting rock has its own unique physical and chemical properties distinct from those of its constituent minerals.
True. Characteristic properties of elements, such as melting point, boiling point, density, and chemical reactivity, do not depend on the amount of material present in a sample of the element. These properties are unique to each element and remain constant regardless of the quantity of the substance.
False. In a physical change, the makeup of matter remains the same, only the physical properties like shape, size, or state are altered. No new substances are formed during a physical change.

The statement that it is characteristic of a scientific theory is that is well tested is false. A scientific theory is a proposed explanation of certain circumstances in nature.
The Field Properties area is displayed in Datasheet view. true or false
That is false.
