Question

Water beads on the outside of a cold glass of water is caused by which of the following?

• A. Water inside the glass transferring to the outside.
• B. Water vapor in the atmosphere condensing onto the glass.
• C. Cold water boiling onto the outside of the glass.
• D. Water from inside the glass freezing onto the glass.

Answer 1

The correct option is B Water vapor in the atmosphere condensing onto the glass.

We see droplets on the outer surface of a glass containing ice-cold water. Because of the high magnitude of low temperature of the glass, it's surrounding becomes cooler than it was before. Due to which, the moisture in the air around the outer surface of the glass condensates, settles down and hence turns into liquid form (water droplets).
