As a beaker of water is heated, it starts to turn into a gas.

Question

Which option correctly shows this phase change?

Responses

H2O (s)
H2O (g)H 2 O ( s ) right arrow H 2 O ( g )

H2O (l)
H2O (g)H 2 O ( l ) right arrow H 2 O ( g )

H2O (s)
H2O (l)H 2 O ( s ) right arrow H 2 O ( l )

H2O (l)
H2O (s)

Answer 1

The correct option that shows the phase change of water from liquid to gas as the beaker of water is heated is:

H2O (l) → H2O (g)

This indicates that liquid water (H2O in the liquid state) is transforming into water vapor (H2O in the gaseous state).
