Question

How you find that in glan
tumber there is hot milk and ice cream is cold​

Answer 1

By touching or observing the surface of the glass tumbler.

Explanation:

• There are two ways to find out if a glass tumbler has hot milk or cold ice cream.

• The first method is to use the sense of touch. It you touch the surface you will be able to find the ingredients of the tumbler.

• The second method is to observe the outer surface of both the tumblers. Suppose there are two tumblers A and B. Tumbler A has hot milk in it, whereas tumbler B has cold ice cream.

• If you leave both the tumblers undisturbed then you will be able to see vapours from tumbler A. The presence of vapours suggest that something hot is present in the tumbler.

• If you are able to see small droplets of water then it contains cold ice cream. As the small droplets are formed due to condensation.
