Molten (liquid) iron cooling and changing to solid iron is an example of:
Water molecules slow down and attractions bring them closer together.
Molecules of different liquids have different amounts of attraction.
Heat transfers from the water to the dry ice.
Water vapor changes from a gas to a liquid.
freezing
The molecules in liquid water are closer together.
water vapor
Water droplets that formed from cooled water vapor in your breath
If you compare solid ice and liquid water on the molecular level, you could say that:
Water molecules slow down and attractions bring them closer together.
Molecules of different liquids have different amounts of attraction.
Heat transfers from the water to the dry ice.
Water vapor changes from a gas to a liquid.
freezing
The molecules in liquid water are closer together.

Chandler is boiling some water to kill the bacteria in it. Chandler notices that there are transparent bubbles forming in the water as she adds heat. The transparent bubbles are:
Water molecules slow down and attractions bring them closer together.
Molecules of different liquids have different amounts of attraction.
Heat transfers from the water to the dry ice.
Water vapor changes from a gas to a liquid.
freezing
The molecules in liquid water are closer together.

If you breathe on a mirror, part of the mirror clouds up. What are you actually seeing when you see the mirror cloud up?
Water molecules slow down and attractions bring them closer together.
Molecules of different liquids have different amounts of attraction.
Heat transfers from the water to the dry ice.
Water vapor changes from a gas to a liquid.
freezing
The molecules in liquid water are closer together.
water vapor
Water droplets that formed from cooled water vapor in your breath
Cooling water vapor makes the water vapor condense faster because:
Water molecules slow down and attractions bring them closer together.
Molecules of different liquids have different amounts of attraction.
Heat transfers from the water to the dry ice.
Water vapor changes from a gas to a liquid.
freezing
The molecules in liquid water are closer together.

When water vapor condenses:
Water molecules slow down and attractions bring them closer together.
Molecules of different liquids have different amounts of attraction.
Heat transfers from the water to the dry ice.
Water vapor changes from a gas to a liquid.
freezing
The molecules in liquid water are closer together.
