Electrostatic forces
________ lower potential energy of a system - SELECTED ANSWER 👀 Attractions
_____ raise potential energy of a system - SELECTED ANSWER 👀 Repulsions
Stable systems form where - SELECTED ANSWER 👀 The attractive and repulsive
forces are EQUAL or the potential energy is at a minimum

, The temperature of a phase change depends on - SELECTED ANSWER 👀 The
strength of the inter molecular forces
Why do two isolated atoms attract each other as they approach and repel after
coming too close together? - SELECTED ANSWER 👀 ?
Predict and explain the changes in the potential energy, the kinetic energy and the
total energy as two isolated helium (or another noble gas) atoms approach each
other. - SELECTED ANSWER 👀 ?
Construct a diagram/picture and use it to explain how energy is transferred at the
atomic level (by collisions that can either add energy to the system or remove it) -
SELECTED ANSWER 👀 ?
Predict/rank the relative London Dispersion Forces between atoms and molecules of
different sizes - SELECTED ANSWER 👀 ?
?Relate the strength of London Dispersion Forces to relative melting and boiling
points for the noble gases or simple diatomic molecules (H2, N2, O2,F2, Cl2, Br2, and
I2) - SELECTED ANSWER 👀 ?
