Is it more convenient to drink hot tea from a glass or aluminum mug?

In order to answer this question, it is necessary to know the specific heat of both materials:

from aluminum = 920 J / kg × ° С

from glass = 840 J / kg × ° С

Let’s compare the values of the specific heat:

920 J / kg × ° С> 840 J / kg × ° С

from aluminum> from glass

Since the specific heat of glass is lower, at the same initial temperature and temperature of tea, it will heat up more slowly than aluminum. From which it follows that tea will also cool more slowly, that is, drinking hot tea is more convenient from a glass mug.
