Question

1. which of the following shows a physical change?

Explanation:

A physical change is a change in which the substance's physical form or appearance changes, but its chemical composition remains the same. Melting ice (assuming the blue object is ice) is a physical change as it changes from solid to liquid without altering its chemical makeup (water remains water). Cooking an egg (B) and burning (C) are chemical changes as new substances are formed. Bending a metal (A) might seem like a physical change, but if it causes oxidation (rusting as shown in the image), it is a chemical change. So the most likely physical - change example here is melting (assuming the blue object is ice).

Answer:

D. (assuming the blue object is ice and represents melting which is a physical change)
