Question

An object was kept outside a shower room which had a glass window. After taking a hot shower, Raj realised, that he was not able to identify the shape of the object. Which phenomena were responsible for this?

• A. Freezing made the windows transparent.
• B. Evaporation made the windows transparent.
• C. Condenstation made the windows translucent.
• D. Evaporation made the windows opaque.

Answer 1

The correct option is C Condenstation made the windows translucent.

• Here, before taking the bath, the glass window was transparent which would have allowed Raj to look at the object clearly.
• However, after taking a hot shower, the water vapours condensed on the surface of the glass, which covered the glass with water droplets and moisture.
• This in turn, impaired Raj's vision and made the glass translucent. Hence, Raj was not able to look at the object clearly.
