States of Matter and Intermolecular Forces Quiz

What is the kinetic theory?

• A theory that describes all matter as tiny particles that are in constant motion

• A theory that describes the motion of particles in a liquid

• A theory that describes the motion of particles in a solid

• A theory that describes the behavior of gases at high temperatures

What type of bonding do compounds like hydrogen sulfide, ammonia, methane, and nitrous oxide have?

• Hydrogen

• Metallic

• Covalent

• Ionic

What type of bonding pattern can be used to predict whether a compound will be a gas at standard temperature and pressure (STP)?

• Hydrogen bonding

• Metallic bonding

• Covalent bonding

• Ionic bonding

What is the result of increasing gas pressure?

• Decreasing the number of collisions

• Decreasing the speed of the particles

• Shrinking the container

• Reducing the number of particles

What units can be used to show pressure?

• Pascal (Pa) and millimeters of mercury (mm Hg)

• Pounds per square inch (PSI) and kilopascals (kPa)

• Atmospheres (atm) and millimeters of mercury (mm Hg)

• Newtons per square meter (N/m^2) and pounds per square inch (PSI)

What is the pressure, in kilopascals and in atmospheres, that a gas exerts at 385 mm Hg?

• 385 kPa and 3.85 atm

• 51.32 kPa and 0.51 atm

• 33.7 kPa and 0.33 atm

• 450 kPa and 4.4 atm

What type of motion is available to molecules in a solid?

• Translation, rotation, and vibration

• Vibration and rotation

• Translation and rotation

• Only vibration

What is the smallest group of particles within a crystal that retains the overall symmetry of the crystal called?

• Crystal lattice

• Unit cell

• Crystal system

• Crystal structure

Why are the structures of solids usually described in terms of the positions of the constituent atoms rather than their motion?

• Because the motion of particles in solids is rotational

• Because the motion of particles in solids is restricted to vibrational motion

• Because the motion of particles in solids is translational

• Because the motion of particles in solids is unrestricted
