What Is Ice?

<동영상보러가기>

Description:

Imagine on a hot summer day, you enjoy sipping a cold drink with little clinking cubes inside - that's ice! Ice is simply water that has gotten so cold it turns solid.

더운 여름날, 얼음이 들어 있는 차가운 음료를 마시는 것을 즐긴다고 상상해 보세요. 얼음은 너무 차가워져서 고체로 변하는 물입니다.​

Transcription:

I Wonder! Ice is formed when water freezes, which happens at 32° F or 0° Celsius.

When the temperature drops below this point, the water molecules slow down and start to stick together, forming a solid structure known as ice.

The unique arrangement of water molecules in ice makes it less dense than liquid water, which is why ice floats on water.

궁금하네요! 얼음은 물이 얼 때 형성되며, 이는 섭씨 32도 또는 섭씨 0도에서 일어납니다.

얼음 속의 독특한 물 분자 배열은 액체 상태의 물보다 밀도가 낮아서 얼음이 물 위에 떠 있는 이유입니다. 

Questions:

1. At what temperature does water typically freeze?

2. What happens to water molecules when the temperature drops below freezing point?

3. Why does ice float on water?​​
