Question

Decrease in vapour pressure will cause?

A. an increase in boiling point
B. a decrease in boiling point
C. no effect ​

Answer 1

A. an increase in boiling point

Step-by-step explanation:

A decrease in vapor pressure will cause an increase in the boiling point of a substance.

An increase in vapor pressure will decrease the boiling point.

• Vapor pressure is a measure of the tendency of a liquid to change into gaseous form.
• The boiling point is the temperature at which the vapor pressure equals the atmospheric pressure.
• When vapor pressure reduces, there would be an elevation of the boiling point.
• This is why pressure cookers causes water to boil faster because they lower the boiling point.
