When I make myself a cup of tea (with teabag + water), it stays too hot to drink for SO LONG. I have to wait for about 10 minutes before I can even bearably drink it.
But when I make myself a hot chocolate (with chocolate powder + milk) it’s drinkable pretty quickly. In fact it goes cold if I don’t drink it quickly enough.
What are the differences in composition of milk vs water which make this the case?

Fat has a much lower heat capacity than water. The heat capacity is how much energy it takes to change the temperature of something. Water’s high heat capacity makes it slow to heat up and cool down.
