Question

Q1. What will happen if you leave a tumbler containing ice cubes at room temperature?​

Answer 1

Answer:

As the ice melts, it cools the water around it. Technically, the ice cube melts because the water cools down. ... However, as the temperature drops below 4 °C the density of water actually begins to decrease and water in this range easily "floats" over water in the room temperature range.

Answer 2

Answer:

There will be condensation of water on the outside of the tumbler, similar to dew on grass. The phenomenon occurs because the water vapour in the air condenses on the outside surface of the tumbler due to a localised heat transfer, reduction of temperature and consequent reduction in the saturated vapour pressure at a given temperature.
