Question

The freezing point and the boiling point of water can be altered by a variety of techniques. Which of the following has little or no effect on the boiling point of water? A: Increasing the air pressure above the liquid B: Adding alcohol to the water C: Adding sodium chloride to the water D: Increasing the amount of water

Answer 1

D: Increasing the amount of water.

Step-by-step explanation:

Choice A: ­ increasing the pressure can force the liquid to stay a liquid and affect the boiling point (decrease it).

Choice B and C: ­ both involve colligative properties, adding a solute to water will increase the boiling point of water.

Choice D: ­ just having more water does not change the boiling point of the water as this minimize the effect of any external factor.

So, the right choice is: D: Increasing the amount of water.
