Option 1: Increasing the atmospheric pressure on a liquid actually increases its boiling point, not lowers it. This is because an increase in pressure makes it harder for the liquid molecules to escape into the gas phase.

Option 2: Lowering the atmospheric pressure on a liquid does indeed lower its boiling point. This is because a decrease in pressure makes it easier for the liquid molecules to escape into the gas phase. When the pressure is reduced, the vapor pressure of the liquid becomes equal to or greater than the atmospheric pressure, allowing the liquid to boil at a lower temperature.

Option 3: This option is incorrect. Lowering the atmospheric pressure on a liquid does affect its boiling point, as explained in option 2.

Option 4: Lowering the atmospheric pressure on a liquid does not directly affect the time required for it to boil. The time it takes for a liquid to boil depends on its heat source, the amount of liquid, and the initial temperature. The boiling point, however, will be lowered at a reduced atmospheric pressure.
