Hello, I am just starting Physics. ( Sophmore in highschool) I need some help, understanding and solving this problem. When you mix hot and cold liquids you can find the temperature of the mixture by using the formula T= ah+bc divided by a+b, where T is the temperature of the mixture, h is the temperature of the hot liquid, c is the temperature of the cold liquid, a and b respresent the amounts of hot and cold liquids. Suppose you mix hot tea and cold milk in a ratio a:b of 9:1 and find that the temperature of the mixture is 117degrees You then change the trea:milk ratio to 2:1 and the temperature drops 96degrees. Find the initial temperatures of the tea and Milk. Again, I can solve it Logically. But using Formula's ( showing your work ) I am not very found of.. Can someone show how to go about this. Thanks!
