Question

A sample of carbon dioxide that undergoes a transformation from solid to liquid and then to gas would undergo _________.

• A. A change in mass
• B. A change in density
• C. A change in composition
• D. No change in physical properties

Answer 1

Answer: (B)

A change in density

We know that,

$Density$ = $\frac{Mass}{Volume}$

Change in state of a substance doesn't alter mass, composition or physical properties but it involves change in volume which results in change in density.
