Question

1. what state of matter was the snow when it fell from the sky?
2. during the day, what role did the sun play in changing the snow on the ground?
3. what happened to the snow when temperatures dropped overnight?
4. why did the snow turn into solid ice instead of staying soft and fluffy?
5. even though snow and ice look different, what substance are they both made of?

Explanation:

1. Snow consists of frozen water crystals, which is a solid state of matter.
2. The sun provides thermal energy that melts solid snow into liquid water.
3. When temperatures drop below freezing overnight, any melted snow (liquid water) freezes back into a solid form.
4. When snow melts from sun/warmth, it becomes liquid water; when this water freezes again overnight, it forms a dense, solid ice structure instead of the loose, crystalline snow.
5. Both snow and ice are frozen forms of water, so their core substance is the same.

Answer:

1. Solid
2. The sun melted the snow into liquid water by providing heat.
3. The melted snow (liquid water) froze back into solid ice.
4. The snow first melted into liquid water from daytime warmth, then this water froze into dense, solid ice when temperatures dropped overnight, rather than reforming the loose snow crystals.
5. They are both made of water (H₂O).
