a) You have a styrofoam container with 815 g of a soft drink (specific heat of 4,100 J/(kg °C)) at 29.0° and you add a 60 g chunk of ice at 0°C. Assume the liquid and water mix uniformly as the ice melts and determine the final temperature of the mixture (in °C). 375.31 X Since the mixture is thermally isolated, the heat gained by the ice and the associated ice water is equal to the heat lost by the liquid. Write expressions for the heat gained by the ice as it changes from a solid to a liquid, gained by the ice water as it warms to the final temperature, and lost by the liquid as it cools to the final temperature. °C b) What If? What is the minimum mass of the ice cube (in g) that will result in a final mixture at exactly 0°C? 290.1 9
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
