When steam condenses, the H2O
1) releases energy.
2) absorbs energy.
3) neither of these.
When water freezes, the H2O
4) releases energy.
5) absorbs energy.
6) neither of these.
Question 2
On cold days your bedroom window may get wet on the inside. This is because
1) the air near the glass becomes saturated.
2) a change in phase from gas to liquid occurs.
3) H2O molecules release energy when they liquify on the glass.
4) fast-moving H2O molecules slow down and condense when they encounter the cold glass.
If the air in the room were colder than the air outside, then quite likely
5) the glass would be even wetter.
6) no wetness would occur.
7) the glass would be wet (or frosty) on the outside surface.
8) none of the above.
