Particle motion in a liquid

Multiple Choice

Water is polar. What does that mean?

• it is a molecule with opposite charges on opposite ends

• it is a molecule with no charge

• it is a molecule with identical charges on opposite ends

• it is a molecule with too many protons

Multiple Choice

Water sticks well to many materials. What term relates to this property of water?

• cohesion

• adhesion

• density

• surface tension

Multiple Choice

Which of the following is an example of COHESION?

• water sticking to water

• water sticking to glass

• oil sticking to plastic

• hydrogen sticking to oxygen

Multiple Choice

What is the term for water's ability to defy gravity and climb up a tube?

• Capillary Action

• Specific Heat

• Universal Solvent

• Magic

Multiple Choice

Why does ice float?

• water expands when it freezes, making ice less dense than water

• water compacts when it freezes, making ice more dense than water

• hydrogen bonds in water push the ice to the surface

• ice is afraid of water, and avoids it

Multiple Choice

Which characteristic of water will allow a paperclip to remain floating on water when the paperclip is gently placed on top of the water?

• adhesion
• surface tension
• solvent properties
• nonpolar

Multiple Choice

A water strider can skate along the top of a pond because:

• covalent bonds result in water cohesion
• hydrogen bonds result in water cohesion (surface tension)
• water striders have adapted to take advantage of water cohesion
• low surface tension of water

Multiple Choice

A water molecule is a _______ since the negative end of one water molecule is attracted to the positive end of another water molecule.

• polar molecule

• sustain life

• surface tension

• specific heat

Multiple Choice

An attraction between molecules of different substances is called...

• adhesion

• cohesion

Multiple Choice

A measure of how difficult it is to stretch or break the surface of a liquid is called...

• specific heat

• polar molecule

• capillary action

• surface tension

Multiple Choice

An attraction between molecules of the same substance is called...

• adhesion

• cohesion

Multiple Choice

Water molecules ________ since the slightly positive portion of a water molecule is attracted to the slightly negative portion of the next water molecule.

• stick together

• spread out

Low-viscosity: water

High-viscosity: Honey

Multiple Choice

Notice how the liquid on the left forms round drops while the one on the right spreads out.

Which phrase describes the difference between the liquids?

• Fixed volume vs changing volume

• Different particle arrangement

• Low-viscosity vs high-viscosity

• Low-surface tension vs High-surface tension

Particle motion in a gas.

Multiple Choice

What is the best way to describe particles in a gas?

• Very energetic

• Vibrating in place

• Completely still

• Closely packed

Multiple Choice

Which of the following depicts particles in a solid?

​Properties of matter

• ​Solids- particles are tightly packed, vibrate in place and have a definite volume and shape.

• ​Liquids- Particles are loose and can move, they have a definite volume, but not a definite shape.

• ​Gases- Particles are spread far and move easily, they have no definite shape or volume

• ​Plasma- particles are loose and can move like water, but have no definite shape or volume like gas and are electrically charged.

​Other properties of liquid

• ​surface tension- the pulling of molecules toward each other.

• ​viscosity- the resistance of flowing

Draw the particle organization of each of the 4 states of matter.

Multiple Choice

What effect does heat have on atomic motion?

• It causes them to vibrate slower

• It causes them to vibrate faster

Multiple Choice

What effect does the loss of heat have on atomic motion?

• It causes them to vibrate faster

• It causes them to vibrate slower

Multiple Choice

Why does a liquid become less dense when heat is added?

• Heat causes the atoms to vibrate slower and move closer together, making the liquid less dense.

• Heat causes the atoms to vibrate faster and move further apart, making the liquid less dense.
