When you are in a hot country and...?

Question

...you have a glass full of ice. The outside of the glass then becomes full of condensation and creates a large pool of water around the glass. Is that in effect the water that was in the glass in ice form? How does the water get from the Ice to a pool of water outside the glass?

PS...This may be on abvious question...but I can't remember the answer.

Answer 1

This is because there can be quite a lot of moisture in warm air. When the (damp) warm air touches the outside of the glass, the air cools and the moisture is no longer able to remain in the air as water vapour - you have subjected it to a temperature below which the air is saturated with water vapour - called the DEW POINT, so it condenses on to the glass.

Very roughly, I seem to remember that air at 20degC can hold up to about 20g/cu.metre water vapour, whereas at 5degC it can hold only about 5g/cu.metre.

Answer 2

By holding a glass of ice in a hot environment, water vapour (gaseous) present in the air near the cold glass condenses to water (liquid).

Its not the water from the ice inside the glass.

Answer 3

This is because difference between temperatures IN the glass and OUT of the glass. Humid in the air is catching on the glass, and that's happening.
Don't take this answer for something important because I just assume that is happening...
