Question

45 A transparent glass window appears hazy when not wiped off regularly. Can you suggest a reason?

Answer 1

• Air is present everywhere and it contains some gases, water vapour, and dust particles in the air adhere to the transparent glass of windows.
• Other outside factors, such as pollen, attract these particles, causing them to collect in the glass and form a coating.
• That is why, if not cleaned regularly, transparent glass seems cloudy.
