Explanation:

1. Which substances from the above freeze in winter?

substances that freeze in winter are alcohol, ghee, water, and coconut oil.
Pure water freezes at 0°.
Coconut oil freezes in winters because it has low melting point of around 24°c. Alcohol does freeze, its freezing point is simply far below that of water.

2. Which substances from above are in liquid state?

Substances in liquid state are water, spirit, petrol, sanitizer and alcohol.

3. Which liquid have you seen change into vapor?

Petrol, or gasoline, evaporates faster than most liquids because of its weak intermolecular attractions.

4. Which solids directly change into the gaseous state?

solid that directly change into the gaseous state are camphor, ammonium chloride, and naphthalene balls.

camphor is a sublime substance and sublime substances are those which are converted into a gas from solid when heated.
naphthalene is a solid that sublimes at standard atmospheric temperature with the sublimation point at around 80°c or 176°F.
