3.3 Solids, Liquids, and Gases

Which of the following states of matter has particles that are close together?

• Plasma

• Gas

• Solid

• Liquid

What is the primary difference between crystalline and amorphous solids?

• Crystalline solids have a regular three-dimensional structure, while amorphous solids do not.

• Crystalline solids have particles that can move freely, while amorphous solids do not.

• Crystalline solids have a fixed volume, while amorphous solids do not.

• Crystalline solids have particles that are far apart, while amorphous solids do not.

Which of the following best describes the motion of particles in a liquid?

• Particles have a fixed volume

• Particles are in constant motion

Which of the following is true about gases?

• Gases have particles that are close together

• Gases have a fixed volume

• Gases can be easily compressed

• Gases have a definite volume and shape

Why are most liquids not easily compressed?

• The particles are relatively close together

• The particles have a fixed volume

• The particles have varying densities

• The particles are in constant motion

What is the triple point?

• The temperature and pressure where a substance occurs as a solid and gas simultaneously at equilibrium

• The temperature and pressure where a substance occurs as a liquid and gas simultaneously at equilibrium

• The temperature and pressure where a substance occurs as a solid and liquid simultaneously at equilibrium

• The temperature and pressure where a substance occurs as a solid, liquid, and gas simultaneously at equilibrium

Why do gases generally follow the ideal gas law?

• Gas particles do not have intermolecular forces

• Gas particles are spaced far apart with minimal intermolecular forces

• All gases have the same volume

• All gases have the same spacing of particles

What is the primary difference between molten iron and solid iron?

• Molten iron has a lower density than solid iron

• Molten iron has particles that are far apart, while solid iron does not

• Molten iron has particles that can move freely, while solid iron does not

• Molten iron has a higher density than solid iron
