Question

(01.02 mc) which of the following will cause a decrease in the mass of an object?
○ increase in the quantity of substance present in the object
○ decrease in the gravitational pull
○ increase in the gravitational pull
○ decrease in the quantity of substance present in the object

Explanation:

Mass is the amount of matter (substance) in an object. Gravitational pull affects weight (force due to gravity), not mass. An increase in substance quantity increases mass, while a decrease in substance quantity decreases mass. So the option with a decrease in substance quantity causes mass to decrease.

Answer:

D. Decrease in the quantity of substance present in the object
