Question

Why do we see water droplets on the outer surface of a glass if cold water is poured into it?

Answer 1

Answer:

Condensation can also produce water droplets on the outside of soda cans or glasses of cold water. When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can. ... Those flat bottoms are where vapor begins to condense into water droplets.

Answer 2

Answer:

$\bold\red{ \: AnswER \: }$

10% of Rs 450 – 12% of Rs 500 + 8% of Rs 500

= (10 / 100 × 450) – (12 / 100 × 500) + (8 / 100 × 500)

= (1 × 45) – (12 × 5) + (8 × 5)

We get,

= 45 – 60 + 40

= 85 – 60

= Rs 25
