I am here again kids.

did you think about the question I asked last time?

The tumbler is made of  a metal and the mug is made of porcelain, a ceramic.

Now why should a metal get hot and why a ceramic should not , is another story. That I will tell a little later.

For a change, let us check what happens if we pour the milk in a saucer.

See which cools faster.

The milk in the mug or that in the saucer.

think think think.
