Honors chemistry final review

Which state of matter does not have a set volume?

• solid

• liquid

• gas

• a rock

Accoridng to Boyle's law, as pressure increases, volume

A gas is originally at a pressure of 3.5 atm, has a volume of 5.6L, and is at a temperature of 26 degrees Celsius. If I raise the pressure to 4.3 atm and a new volume of 8.1L, what is the new temperature in Kelvin?

• 531K

• 1079K

• 253K

When can liquid particles escape a liquid and become gas particles?

• When the liquid particles reach dynamic equilibrium.

• When sublimation occurs.

• When they gain enough kinetic energy to overcome attractive forces of the liquid.

• When the liquid is over 200 degrees Celsius.

On a phase diagram, what does the triple point represent?

• Melting- going from a solid to a liquid.

• vapor liquid equilibrium line

• Only the gaseous state exists at temperature and pressure above this point.

• A point at which all three states of matter exist in equilibrium.

Which best describes the difference between intermolecular and intramolecular forces?

• Intramolecular forces are bonds between atoms within a compound, while intermolecular forces are forces between neighboring atoms.

• Intermolecular forces are bonds between atoms within a compound, while intramolecular forces are forces between neighboring atoms.

• Intermolecular forces are ionic, while intramolecular forces are covalent.

• Intermolecular forces are found in liquids, while intramolecular forces are only found in solids.
