17 Questions
According to Kinetic Molecular Theory, what is the relationship between kinetic energy and temperature?
Kinetic energy increases as temperature increases.
In which state of matter are molecules held together by attractive forces and have very little empty space?
Liquid
Which state of matter has molecules that are held rigidly in position?
Solid
What happens to the distance between molecules when transitioning from a liquid to a gas state?
The distance increases.
Which phase of matter is harder to compress than gases?
Liquid
What type of order characterizes many solids?
Long-range order
Which state of matter flows, can be poured, and assumes the shape of its container?
Liquid
What type of forces are responsible for the attractive interactions between polar molecules?
Dipole-dipole forces
Which type of force is significant only when atoms are close together?
London dispersion forces
What type of bond involves interactions between hydrogen and an electronegative atom like O, N, or F?
Hydrogen bond
Which force involves electrostatic interactions between a fixed dipole in one molecule and an ion in another?
Ion-dipole forces
Why are dipole-dipole forces stronger than London dispersion forces?
Because they have a permanent uneven distribution of electrons
What causes London Dispersion Forces to occur between nonpolar molecules?
Permanent dipole moments induced by electron movement
What factor influences the strength of dispersion forces in molecules?
Size and diffuseness of the electron cloud
Which molecule would likely have stronger London Dispersion Forces with another molecule?
Iodine (I2)
How does an increase in the number of atoms in a molecule affect its intermolecular forces?
Increases the strength of dispersion forces
What property of molecules determines their polarizability?
Ease with which electron distribution can be distorted
Test your knowledge on the postulates of the Kinetic Molecular Theory (KMT) which explains the behavior of matter, including concepts like particle motion, kinetic energy, temperature, space between particles, and phase changes.
