The process of breaking rock into smaller pieces without altering its chemical composition is called mechanical weathering. This can occur through various physical forces, such as freeze-thaw cycles, abrasion, thermal expansion, or root growth. These mechanisms physically fragment the rock, but the mineral composition remains unchanged, distinguishing it from chemical weathering, which involves alterations at the molecular level.
The property least likely to be affected by weathering of a mineral is its crystal structure. While weathering can alter other characteristics such as color, hardness, and luster due to physical or chemical changes, the fundamental arrangement of atoms in the crystal lattice remains largely intact unless the mineral is completely broken down. This stability in crystal structure allows the mineral to retain its identity despite surface alterations.
None: The catalyst remains unchanged, but the catalyst also speeds up the reaction.
Yes, crushing limestone is a physical change. This is because the chemical composition of limestone remains unchanged during the process of crushing. The size and shape of the limestone particles may change, but the chemical makeup remains the same.
The mineral composition of a rock remains unchanged by mechanical weathering, which only affects the physical structure of the rock by breaking it into smaller pieces or changing its shape.
Technically, they do remain unchanged. But as physical weathering of rocks progresses, it can expose the minerals in the cracks to the elements resulting in the disintegration of the rock. The mineral makeup of the rock will then change to agree with the surrounding environment.
The total mechanical energy of the projectile remains unchanged during its flight. This includes both kinetic energy and potential energy.
The frequency of a wave remains unchanged when it enters a different medium. This means that the number of oscillations or cycles that the wave undergoes per unit time remains the same.

This is the Identity Property so it is the the Additive Identity and Multiplicative Identity.

The mass of the object remains unchanged, as it depends only on the amount of matter in the object.
A static character remains essentially unchanged throughout the action of a story. They typically do not undergo significant development or transformation.
The property illustrated by the expression ( 65 \times 1 = 65 ) is the Multiplicative Identity Property. This property states that any number multiplied by one remains unchanged. In this case, multiplying 65 by 1 confirms that 65 retains its original value.
