What happens to the vapor pressure as more solute, such as sugar, is added to a solution?
a. the vapor pressure increases
c. the vapor pressure does not change
b. the vapor pressure decreases
d. the vapor pressure will increase at first, then it will decrease

Colligative properties will be exhibited by the solution specifically vapor pressure lowering. Therefore, the correct answer among the choices given is option B. The vapor pressure decreases. This is because the number of solvent molecules near the surface decreases which makes it hard to be pushed to the vapor phase.

D. most models represent a real world object in a simpler way

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.
