Question

2. If the glass tumbler, containing the cold lemonade, is kept on the table for
sometime, what change will be observed?​

Answer 1

Answer:

become normal temperature

Explanation:

because it was cold after sometime it gets hotter.

Answer 2

The change observed in this case is that the water droplets will form on the glass of cold lemonade.

• When any cold thing is kept at a temperature that is higher than that the formation of water droplets is observed on the surface.
• The water vapour that is present in the atmosphere when comes in contact with cold glass, in this case, condenses to the liquid state.
• This is because when vapour is exposed to colder temperatures it converts into liquid form through state change and the process is called condensation.
• The droplets of water formed on the glass surface are the water vapour that got converted to liquid droplets on coming in contact with cold temperature.
• Hence, it is a physical change where vapour in the atmosphere is condensed to droplets on lemonade glass when it is kept outside on a table.
