The process that changes a solid directly into a gas is called sublimation. A solid that begins with a mass of 450 g will sublime to give off a gas with a mass of _______ g.

Question

A.
450
B.
0
C.
900
D.
45

Answer 1

The correct answer is A. 450 g.

Sublimation is a phase change where a solid turns directly into a gas without passing through the liquid phase, and the mass of the substance remains the same during this process. Therefore, if a solid with a mass of 450 g sublimates, it will produce gas with a mass of 450 g as well.
