Answer

Option B= physical changes

Explanation

Because in case of physical changes mass of substance and even the internal properties of the molecule remain same. Temporary changes occur that affects only physical properties of the material like size, colour and shape etc. No new substance is formed, that means the molecules and atoms are arranged in the same way in products as were in reactants.

While in case of endothermic changes new chemical bonds are formed due to breaking of existing bonds and atoms are rearranged permanently.

Lucia is playing with magnetic toy vehicles. She has two identical toy vehicles (purple and pink) that start on opposite sides o
pentagon [3]

Answer:

The potential energy of both toy vehicles (purple and pink) decreased. Since the pink toy was moved closer to the magnet, it will have less potential energy because of the short distance it will take to travel to the magnet. Although the purple toy is now closer to the magnet, it is still pretty far and will have a somewhat big potential energy when traveling to the magnet.

Explanation:
