In this video, I will solve some exercises on Heat Exchange (with phase changes). Do you want to learn everything about Calorimetry? Sign up! LINK TO MY PHYSICS PLATFORM: ➡️ https://linktr.ee/Prof.Davi Exercise 01 An ice cube at 0°C is placed in 200 g of water at 30°C, in a container with negligible heat capacity and thermally insulated. Thermal equilibrium is established at 20°C. What is the mass of the ice cube? Exercise 02 A buffet was hired to serve 100 guests at an event. Among the items on the menu was water at 10°C. Knowing that the buffet had in stock 30 liters of water at 25°C, determine the amount of ice, in kilograms, at 0°C, necessary to obtain water at a temperature of 10°C. Consider that the water and ice are in an isolated system. Exercise 03 40 g of ice at 0°C are placed in 100 g of water at 20°C contained in a calorimeter with negligible heat capacity. When thermal equilibrium is reached, determine: a) the temperature; b) the mass of water in the calorimeter.
