Question

11. You are in the frozen food section of the grocery store and you notice that your hand gets cold when you place it on the glass windows of the display cases. Your friend says this is because coolness is transferred from the display case to your hand. What do you think?

Answer 1

Glass is cold and hands are warm that's why

Answer 2

Yes, your friend is right because the temperature whether it is hotness or coolness passes from one medium to another and at that time the first medium was display glass and the other medium was your hand. So the coolness came to your hand.
The first medium that was glass was cool and the other medium that was your hand was comparitively hot. So the cold temperature particals moved to the hot temperature particals
