States of Matter Review

Multiple Choice

Which of the following is a key property of solids?

• Definite shape and volume

• No definite shape

• Particles slide freely

• Volume changes with container

Multiple Choice

What distinguishes a crystalline solid from an amorphous solid?

• Crystalline solids lack a regular pattern

• Amorphous solids have a defined melting point

• Crystalline solids have particles arranged in a regular, repeating pattern

• Amorphous solids maintain a fixed shape

Multiple Choice

What characteristic best describes liquids?

• Fixed particle positions

• Definite volume but takes the shape of its container

• Widely spaced particles

• Higher viscosity than solids

Multiple Choice

Which statement best describes surface tension and viscosity?

• Surface tension is the liquid's resistance to flow, and viscosity is the attraction among molecules at the surface

• Surface tension is the attraction among liquid molecules at the surface, and viscosity is the liquid's resistance to flow

• Both surface tension and viscosity refers to the same property of a liquid

• Surface tension and viscosity only occur in gases

Multiple Choice

What happens to the volume of a gas when placed in a different container?

• Remains constant

• Changes to fill the container

• Becomes fixed

• Decreases significantly

Multiple Choice

How does increasing thermal energy affect particle motion in matter?

• Particles slow down and settle in place

• Particles gain kinetic energy and move faster

• Particles become fixed in position

• There is no change in particle motion

Multiple Choice

How does 3D printing demonstrate the change in state of matter?

• It uses heat to melt solids into liquids and solidify them

• it freezes liquids into solids

• it compresses gases into solids

• it turns gases into liquids

How confident are you feeling?

• I have mastered states of matter

• I still find it hard to understand the difference

• This was tough, i'll need another lesson
