It is non-polar molecule.
CF₄ - dipole moment = 0D
Doubling the amplitude of a wave means that you increase the energy of a wave factor of quadrupling
Answer:

Explanation:
= Initial pressure = 931 torr = 
= Final pressure = 113 kPa
= Initial volume = 350 mL
= Final volume
From the Boyle's law we have

The volume the gas would occupy is
.
