Question

Unit Problem: A sample of an unknown metal (c = 0.285 J/g*K) is heated to an initial temperature of 81.9 °C. It is added to a 28.49 g sample of water (c = 4.184 J/g*K), raising the temperature of the water from 24.7 °C to a final temperature of 28.6 °C. What is the mass of the metal, assuming no heat is lost to the calorimeter? A) Hypothesis: State your strategy for how to solve the problem in 2-4 sentences. Note that this should be targeted toward the specific example you are solving (i.e., do not just give a vague overview that could apply to solving any problem), but also should not go into the details or step-by-step instructions (save this for part D) B) Experimental Design: State three definitions and/or problem-solving rules that are necessary to complete the problem (1-2 sentences each). Ensure that you connect the rule/definition specifically with how it will be applied in the problem. See the Sample Quiz for examples. C) Solve: Complete the provided problem, showing all steps involved. This will often be best done by handwriting your work and including a picture of this work, rather than attempting to format within this Word document. This section should not include sentence explanations for the steps taken. D) Explanation: Explain, in 6-10 complete sentences and in your own words, all of the steps and considerations used to solve the problem above.

Solve the following problem. 1. Suppose a piece of iron with a mass of 21.5 g at a temp of 100.0 °C is dropped into an insulated container of water. The mass of the water is 132.0 g and its temperature before adding the iron is 20.0 °C. What will be the final temp of the system? Specific heat of iron is 0.449 kJ/kg K. 2. A 25.95 g sample of methanol at 35.60 °C is added to a 38.65 g sample of ethanol at 24.70 °C in a constant-pressure calorimeter. If the final temperature of the combined liquids is 28.65 °C and the heat capacity of the calorimeter is 19.3 J/C, determine the specific heat of methanol. 3. A student heats a piece of 130 g of an unkown grayish metal to a temp. of 99.2 °C. she places the metal in a styrofoam cup that contains 55.7 g water at a temperature of 23.0 °C. The hot metal heats the water in the cup to 31.4 °C. 4. The temperature inside a sauna is 85.0°C. If 235.0g of solft drink straight from refrigerator (assumed to be at a temperature of 50.0°C) is brought into the sauna, how much heat will be absorbed by the soft drink? Assume that the specific heat of the soft drink is the same as that of water, 4.19kJ/kg°C.

9.31 A metal radiator is made from 26.0 kg of iron. The specific heat of iron is 0.449 Jg C How much heat must be supplied to the radiator to raise its temperature from 25.0 to 55.00 9.32 The material typically used to heat metal radiators is water: If a boiler mass of water Was needed to generates water at 79.5*C, what provide the heat required in the heat of +.184 Jg previous problem? Water has # specific 933 Copper wires used to transport electrical current heat up because of 140-g wire gains 280 J of heat; what is the the resistance in the wire. If a change in heat of 0.384 Jg temperature in the wire? Copper has a specific 9.34 A copper nail and an iron nail of the same mass and at the same room temperature are both put into a vessel initially containing boiling water; Which one would you expect to reach 100°C first? Why: 9.35 A piece of titanium metal with a mass of 20.8 g is heated in boiling water to 99.5°C and then dropped into a coffee cup calorimeter containing 75.0 g of water at 21.7°C. When thermal equilibrium is reached, the final temperature is 24.3°C. Calculate the specific heat capacity of titanium. 9.36 Define the term calibration. 9.37 A calorimeter contained 75.0 g of water at 16.95°C. A 93.3-g sample of iron at 65.58°C was placed in, giving a final temperature of 19.68°C for the system; Calculate the heat capacity of the calorimeter. Specific heats are 4184 Jg°C for H2O and 0.444 Jg°C for Fe. 9.38 The energy densities of various types of coal are listed below: Anthracite 35 kJ/g Subbituminous 31 kJ/g Bituminous 28 kJ/g Lignite 26 kJ/g
