Balloon and Treacle

The video tutorial explores static electricity and its effects on materials. It demonstrates how a charged balloon can influence the flow of water and treacle due to electrostatic attraction. The tutorial explains the concept of polar molecules and how they align in response to a charged object. Additionally, it discusses practical applications of electrostatic attraction, such as reducing air pollution in smokestacks by charging smoke particles to capture them effectively.

What materials are required to demonstrate the effects of static electricity?

• Balloons, water, sugar, funnel, and burette

• Balloons, water, honey, funnel, and burette

• Balloons, sand, oil, funnel, and burette

• Balloons, water, treacle, funnel, and burette

How does rubbing a balloon against hair affect its charge?

• It becomes neutral by losing electrons

• It becomes negatively charged by gaining electrons

• It becomes positively charged by gaining electrons

• It becomes positively charged by losing electrons

Why is water attracted to a negatively charged balloon?

• Water molecules are negatively charged and repel the balloon

• Water molecules are polar and align with the balloon

• Water molecules are non-polar and align with the balloon

• Water molecules are positively charged and repel the balloon

What role do sugar molecules play in the treacle experiment?

• They make the treacle positively charged

• They make the treacle non-polar

• They prevent the treacle from flowing

• They help maintain the stream of liquid

How can electrostatic attraction help reduce air pollution?

• By converting smoke particles into harmless gases

• By charging smoke particles to attract them to electrodes

• By neutralizing smoke particles

• By dispersing smoke particles into the atmosphere
