Question

which action involving bread is a physical change?
baking a loaf of bread
cutting a slice of bread
burning a piece of toast

Explanation:

A physical change alters the form or appearance of a substance without changing its chemical composition. Baking bread involves chemical reactions (e.g., yeast fermentation, Maillard reactions). Burning toast is a chemical change (combustion, producing new substances like carbon dioxide). Cutting bread only changes its physical form (size, shape) without altering its chemical makeup.

Answer:

Cutting a slice of bread
