Question

breaking aluminum foil slicing a mango carving plastic rusting of iron (fe) burning paper snow melting bleaching hair frying a chicken physical change chemical change

Explanation:

Step1: Recall physical - change definition

Physical change is a change in which the substance changes form or state but not its chemical composition.

Step2: Recall chemical - change definition

Chemical change is a change in which a new substance is formed with different chemical properties.

Step3: Analyze tearing aluminum foil

Tearing aluminum foil only changes its shape, not its chemical composition. So it is a physical change.

Step4: Analyze slicing a mango

Slicing a mango only changes its physical form, not its chemical nature. So it is a physical change.

Step5: Analyze carving plastic

Carving plastic only modifies its shape, not its chemical makeup. So it is a physical change.

Step6: Analyze rusting of iron

Rusting of iron (Fe) forms iron oxide, a new substance with different chemical properties. So it is a chemical change.

Step7: Analyze burning paper

Burning paper produces ash, carbon - dioxide, and water vapor, new substances. So it is a chemical change.

Step8: Analyze snow melting

Snow melting changes water from solid to liquid state without changing its chemical composition. So it is a physical change.

Step9: Analyze bleaching hair

Bleaching hair involves chemical reactions that change the color and chemical structure of hair pigments. So it is a chemical change.

Step10: Analyze frying a chicken

Frying a chicken causes chemical reactions like protein denaturation and Maillard reactions, forming new substances. So it is a chemical change.

Answer:

Physical change: tearing aluminum foil, slicing a mango, carving plastic, snow melting
Chemical change: rusting of iron (Fe), burning paper, bleaching hair, frying a chicken
