Solids, Liquids, Gases Quiz

Question 1

What is viscosity? Compare the viscosities of honey and water.

Answer 1

Viscosity is a liquid’s resistance to flowing. Honey’s viscosity is lower than that of water.

Question 2

What is the difference between evaporation and boiling?

Answer 2

When a liquid evaporates, the vaporization occurs only on the surface of the liquid. When a liquid boils, the vaporization occurs below and at the surface of the liquid.

Question 3

What happens to the particles in a substance when heat is transferred to that substance?

Answer 3

When heat is transferred to a substance, the kinetic energy in the substance increases (the molecules move faster), producing more heat.

Question 4

Indicate which states have a gain or loss of thermal energy.

Answer 4

Freezing: loss
Melting: gain
Condensation: loss
Sublimation: gain
Vaporization: gain
Deposition(gas to solid): loss

Question 5

What are the differences between amorphous and crystalline solids?

Answer 5

Amorphous: becomes softer and softer or changes form; no melting point; no specific pattern to its shape
Crystalline: begins to melt/change form at a certain temperature; melting point; formed in a certain pattern

Question 6

Give examples of amorphous and crystalline solids.

Answer 6

Amorphous: Butter, Wax, Ice Cream, Plastic, Rubber, etc.
Crystalline: Sand, Salt, Snow, Glass, Sugar, etc.

Question 7

Temperature vs. Thermal Energy

Answer 7

Temperature: an average measure of kinetic energy

Thermal energy: a total measure of kinetic energy

Question 8

Solids, Liquids, Gases: what are the properties of each?

Answer 8

Solids: 1)Particles in a solid vibrate in place.
2)Shape is definite.
3)Volume is definite.
Liquids: 1)Particles move freely around each other, but are still close together
2)Shape is indefinite.
3)Volume is definite.
Gases: 1) Particles move freely in all directions.
2)Shape is indefinite.
3)Volume is indefinite.
