Explanation:
Step1: Recall water's freezing point
Water freezes at 0°C. At - 12°C, it is solid.
Step2: Know plasma state
Stars are in plasma state at high - temperatures like 500000°C.
Step3: Consider gasoline's state
Gasoline is liquid at room - like temperatures (30°C).
Step4: Determine helium's state
Helium is a gas at normal conditions and at - 20°C.
Step5: Analyze wood's state
Wood is solid at 100°C.
Step6: Identify urine's state
Urine is liquid at body - temperature (37.2°C).
Step7: Find oxygen's state
Oxygen is gas at high temperatures like 1400°C.
Step8: Check cooking oil's state
Cooking oil is liquid at 10°C.
Step9: Classify carbon monoxide
Carbon monoxide is a compound of carbon and oxygen.
Step10: Classify air
Air is a homogenous mixture of gases.
Step11: Classify gasoline
Gasoline is a homogenous mixture of hydrocarbons.
Step12: Classify iron
Iron is an element.
Step13: Classify wood
Wood is a heterogeneous mixture of different compounds.
Step14: Classify quartz
Quartz (silicon dioxide) is a compound.
Step15: Classify oxygen
Oxygen is an element.
Step16: Classify a person
A person is a heterogeneous mixture of different substances.
Step17: Classify mass
Mass depends on the amount of matter, so it's extensive.
Step18: Classify body length
Body length depends on the size of the object, so it's extensive.
Step19: Classify melting point
Melting point is the same for a substance regardless of amount, so it's intensive.
Step20: Classify corrosion resistance
Corrosion resistance is a characteristic of the material itself, so it's intensive.
Step21: Classify density
Density is the same for a substance regardless of amount, so it's intensive.
Step22: Classify volume
Volume depends on the amount of matter, so it's extensive.
Step23: Classify water freezing
Water freezing is a physical change as no new substances are formed.
Step24: Classify acid - base reaction
Acid - base reactions form new substances, so it's a chemical change.
Step25: Classify an object's color
Color is a physical property.
Step26: Classify reactivity
Reactivity is a chemical property as it involves chemical reactions.
Step27: Classify making a shaped incision
Making a shaped incision is a physical change as no new substances are formed.
Step28: Classify corrosion resistance
Corrosion resistance is a chemical property as it involves chemical reactions with the environment.
Step29: Classify an object's mass
Mass is a physical property.
Step30: Classify stretching spandex
Stretching spandex is a physical change as no new substances are formed.
Step31: Classify digestion
Digestion involves chemical reactions to break down food, so it's a chemical change.
Step32: Classify the texture of an object
Texture is a physical property.
