Section 5 Review

Solids, liquids and gasses have kinetic energy due to the way their atoms move, what form of molecular motion do solids experience?

• Translational

• Vibrational

• rotational

• transitional

which statement is true about ice and water?

• Ice is more dense than water that is why ice floats

• water is more dense than ice that is why ice floats

• Ice and water have the same density that is why ice floats

• Ice does not float in water because it is a solid

Sublimation is defined as when a solid changes directly into a gas, due to the

• weak hydrogen bonds

• weak dipole interactions

• weak dispersion forces

• weak ionic bonds

Would the solubility be saturated, super saturated or unsaturated for KNO3 if we had 50g of solute at 50 degrees Celsius?

• Unsaturated

• Super Saturated

• Saturated

• All of the above

Which of the following compounds would not conduct electricity when dissolved in water?

• MgF2

• Na2S

• C12H22O11

• C2H5OH

As we increase the temperature in a GAS lice oxygen or carbon dioxide the solubility would

• Increase

• Decrease

• fluctuate

• stabilize

The triple point of the phase diagram shows

• where solids changes to a gas

• where a gas changes to a solid

• where a gas, solid and liquid exist at equilibrium

• where a gas changes to a solid

Which of the following has the lowest melting point?

• Ionic compound

• Covalent network solids

• Molecular compounds

Which of the following has the highest melting point?
