Question BELOW?

Question

how does a substance, such as glass, become the same temperature of the substance it is being heated or cooled in for about eight to ten minutes?
what is the name of this property?





******ADDITIONAL IF YOU DO NOT UNDERSTAND WHAT I AM ASKING OF YOU**********
if you do not understand the the first part of the question, i have provided an example below:
if i was heating a beaker with glass enclosed in it (through rubber stopping or suctioning) by completely submerging the beaker into the water bath, how does the beaker, then obtain the same temperature as the water bath within eight to ten minutes? could you please make sure to tell what the name of this property is called?





THANK YOU EVER SO MUCH!!!!:)
I OFFER MUCH GRATITUDE TO YOU!

Answer 1

This property is called thermal conductivity. Some materials conduct heat very well, like metals, and glass, while other are very poor at conducting heat - like polymers.

Here's a little more about it:

Answer 2

There are three types of heat transfer Conduction, Convection, and Radiation. In the case you described above you are getting your heat transfer through conduction and if boiling is present convection is also happening.
