Density and Properties of Ice

Esther explains why icebergs float by discussing the concept of density. She compares icebergs to ice cubes in a drink, highlighting that icebergs are less dense than water, which allows them to float. An experiment is conducted to show how water expands and becomes less dense when it freezes. The video concludes with a summary and encourages viewers to vote on future topics.

What is an iceberg primarily made of?

• Sand

• Salt

• Ice

• Rock

Why do icebergs float despite their massive size?

• They are pushed by ocean currents

• They are less dense than water

• They are anchored to the sea floor

• They are lighter than air

What happens to water when it freezes?

• It becomes denser

• It changes color

• It expands

• It evaporates

In the experiment, what was observed when the water bottle was frozen?

• The water evaporated

• The top of the bottle popped off

• The water changed color

• The bottle shrank

What is the scientific term for the measure of how much mass is contained in a given volume?

• Mass

• Volume

• Density

• Weight

Why does a penny sink in water while an iceberg floats?

• A penny is less dense than water

What happens to the density of water when it freezes?

• It decreases

• It becomes zero

• It increases

• It remains the same

What is the main reason icebergs float in the ocean?

• They are pushed by wind
