I WONDER - Is Ice Cloudy Or Clear?

The video explains why some ice cubes are clear while others are cloudy. Clear ice forms when water freezes slowly and evenly, allowing air bubbles and impurities to escape. In contrast, cloudy ice forms when water freezes quickly, trapping air bubbles and impurities. This is why ice made in home freezers is often cloudy, while ice in restaurants and bars is usually clear.

What is the main question raised in the introduction of the video?

• Why are some ice cubes clear while others are cloudy?

• How is ice made in restaurants?

• Why do some ice cubes melt faster than others?

• What is the best way to freeze water?

What condition is necessary for the formation of clear ice?

• Water must be boiled before freezing.

• Water must freeze quickly.

• Water must freeze slowly and evenly.

• Water must be shaken before freezing.

What happens to air bubbles and impurities during the formation of clear ice?

• They escape as the water freezes.

• They dissolve in the water.

• They form a layer on top of the ice.

• They are trapped within the ice.

How does the freezing process differ for cloudy ice compared to clear ice?

• Cloudy ice forms when water freezes slowly.

• Cloudy ice forms when water freezes quickly.

• Cloudy ice forms when water is filtered.

• Cloudy ice forms when water is stirred.

Why is ice made in restaurants usually clear compared to ice made at home?

• Restaurants use a slow and even freezing process.

• Restaurants freeze water more quickly.

• Restaurants add chemicals to the water.

• Restaurants use special water.
