when temperature rises, some matter turns from solid to liquid. imagine a chocolate bar melting in your hand on a hot day—the liquid drips down your fingers. when you add heat to a liquid, like boiling water on a stove, it becomes gas. but did you know there is a type of ice that does not melt at all? it changes from a solid to a gas. let us find out how!
the science behind the \smoke\
dry ice is different from the ice you find in a freezer. it is actually a frozen gas called carbon
question 1 of 3
1 when does sublimation happen?
a when dry ice melts into water
b when dry ice turns into gas
c when dry ice boils on a stove
d when dry ice touches skin

Explanation:

Sublimation is the process by which a substance changes directly from a solid to a gas without passing through the liquid state. Dry - ice (solid carbon dioxide) sublimates, turning directly into carbon - dioxide gas. Option A is melting (solid to liquid), option C is boiling (liquid to gas), and option D is not a phase - change related to sublimation.

Answer:

B. When dry ice turns into gas
