Why Do Bubbles Form In A Glass Of Water?

The video explains why bubbles form in tap water left at room temperature. It discusses how gases like nitrogen and oxygen dissolve in water under high pressure and low temperature, and how their solubility decreases as temperature rises. This phenomenon affects aquatic life, as warmer water holds less oxygen, impacting fish survival. Human activities, such as power plants discharging hot water, exacerbate this issue. The video also covers how increased pressure enhances gas solubility, using carbonated drinks as an example. Overall, it highlights the importance of temperature and pressure in gas solubility.

What conditions make tap water ideal for dissolving gases like nitrogen and oxygen?

• Low pressure and high temperature

• High pressure and high temperature

• Low pressure and low temperature

• High pressure and low temperature

How does the solubility of gases in water change with temperature?

• It increases as temperature rises

• It decreases as temperature rises

• It remains constant regardless of temperature

• It fluctuates randomly with temperature

Why is it important for water temperatures to remain low for aquatic organisms?

• Low temperatures reduce water pollution

• Low temperatures ensure sufficient dissolved oxygen

• Low temperatures prevent algae growth

• Low temperatures increase the water's salinity

What human activity is mentioned as a cause for rising water temperatures affecting aquatic life?

• Urban development

• Agricultural runoff

• Power plant discharge

• Deforestation

How does increased pressure affect the solubility of gases in water?

• It has no effect on solubility

• It decreases solubility

• It causes gases to evaporate

• It increases solubility
