Decrease in vapour pressure will cause? A. an increase in boiling point
B. a decrease in boiling point
C. no effect

A. an increase in boiling point

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.

If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .
