You are given three samples: copper wire, saltwater, and a salad. Explain how you would classify each as a pure substance, homogeneous mixture, or heterogeneous mixture.
Copper wire: pure substance; saltwater: homogeneous mixture; salad: heterogeneous mixture
Copper wire: heterogeneous mixture; saltwater: pure substance; salad: homogeneous mixture
Copper wire: homogeneous mixture; saltwater: heterogeneous mixture; salad: pure substance
Copper wire: pure substance; saltwater: heterogeneous mixture; salad: homogeneous mixture
A scientist observes that the particles in a sample are tightly packed and vibrate in place. The sample also has a definite shape and volume. What state of matter is being described, and what does this indicate about the kinetic energy of its particles?
Solid; low kinetic energy
Liquid; high kinetic energy
Gas; very high kinetic energy
Plasma; extremely high kinetic energy
A mixture of oil and water is left to stand. After some time, two separate layers form. What type of mixture is this, and what does this tell you about the properties of oil and water?
Homogeneous mixture; oil and water have similar properties
Heterogeneous mixture; oil and water do not mix due to different properties
Pure substance; oil and water are the same substance
Solution; oil dissolves in water
