PROBLEM 5-8 points You are making iced tea. The tea itself is initially at a temperature of 50.0 °C. You then toss in an ice cube with a mass of 50 and an initial temperature of -20.0 °C. The ice cube melts, and the final temperature of the mixture is +30.0 °C. For this problem, use the following values: c for liquid water is 4000 J/(kg "C), c for solid water is 2000 J/(kg°C), and the latent heat of fusion...

Temperature Change and Heat Capacity - Calorimetry- Two substances The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat c is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C....

Hint for Part C:
5. 1792 Russell Biven decides to make some iced tea. He starts with 6 liters of water at 17°C. Assume that the properties (heat coefficients, density, etc) for iced tea are the same as for water. Ignore the pot when making calculations. Example 1 Example 2 MIX NEN NTH H Part Chk History Description Answer Russell starts by bringing the 6 liters of water to a boil. How much heat A: needs to be added to...

Calculate the final equilibrium temperature when 10.0 grams of steam initially at 100 degree C is mixed with 450 grams of liquid water and 110 grams of ice at 0 degree C in a calorimeter. That is, the liquid water AND the ice are initially at 0 degree C. Ignore any heat energy exchanges with the calorimeter and the surroundings. If you conclude that the final temperature of the system is 0 degree C, then what mass of ice remains,...

The specific heat c is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C. The specific heat c is a property of the substance; its Sl unit is J/(kg · K) or J/(kg.°C). Recall that the temperature change (AT) is the same in units of kelvin and degrees Celsius. water silver copper cup Case 1: A 0.780-kg silver pellet with a temperature of 85 °C is added to 0.150 kg of water in...

In a gas turbine engine, the compressor takes in air at a temperature of 15°C, pressure of 100 kPa, and a volumetric flow rate of 5 m3 /s and compresses it to four times the initial pressure with an isentropic efficiency of 82%. The air then passes through a heat exchanger heated by the turbine exhaust before reaching the combustion chamber. In the heat exchanger 78% of the available heat is given to the air. The maximum temperature after constant...

An aluminum block of mass 500 g is heated to a temperature of 150 C and droped into a cup of water of mass 1500 g. The heat capacity of the cup is 100 cal/K. Assuming that the initial temperature of the cup and water is 20 C, find the final temperature of the system after it reaches thermal equilibrium.
