Liquid State of Matter & Vanderwaals Forces

liquid is defined as:

• A substance that flows freely but is of constant volume.
• A substance that has a variable volume.
• A substance that is neither solid nor gas.
• A substance that is solid at room temperature.

The molecules of liquid possess motion known as:

• Kinetic motion
• Brownian motion
• Static motion
• Translation motion

which statement about the compressibility of liquids is true:

• Liquids are less compressible than gasses.

• Liquids cannot be compressed at all.
• Liquids have a high compressibility compared to gases.
• Liquids can be easily compressed.

When liquid is cool down it:

• solidifies
• expands
• contracts

• evaporates

When you step into a swimming pool, the water is

• No change in any property of water

• expands due to your weight

• compressed due to your weight

• density of water increases

When you drop a drop of food coloring into a glass of water, the food coloring will eventually spread throughout the water due to:

• diffusion of liquid

• condensation of liquid

• gravity
• evaporation of liquid

Brownian motion is defined as:

• Motion of particles in a vacuum
• Motion of particles in a solid
• Random motion of particles suspended in a fluid due to unequal number collision of liquid molecules with each other from different sides

• Motion of particles in a gas

The inter molecular forces in liquid:

• The inter molecular forces are negligible.

• are stronger than in solids but weaker than in gases.

• The inter molecular forces in liquids, gases, and solids are all equal.

• are stronger than in gases but weaker than in solids.

A metal that exist in liquid state at room temperature is:

• Gold (Au)

• Mercury (Hg)

• Aluminum (Al)

• Iron (Fe)

A non metal that exist in liquid state at room temperature is:

• bromine
• oxygen
• nitrogen
• hydrogen
