To determine the specific heat of an object, a student heats it to 100 ∘C in boiling water. She then places the 87.2 g object in a 173 galuminum calorimeter containing 136 g of water. The aluminum and water are initially at a temperature of 19.8 ∘, and are thermally insulated from their surroundings. If the final temperature is 23.4 ∘, what is the specific heat of the object? Referring to the table, identify the material in the object. Substance...

Useful equations and constants: heat lost/gained = (Volume (Density)(AT)(specific heat capacity) (heat lost by hot water) - Cheat gained by cold water) calorimeter constant = Density co = 1.00 g/mL Specific heat capacity (water) - 4.184 J/g °C 1. What is thermochemistry? (2 pts) 2. A student adds 5.00 mL of cold water to 5.00 mL of hot water in a test tube surrounded by a Styrofoam installation (ie, calorimeter). The initial temperature of the cold water was 15.26 °C,...

(b) If 3.0% of the heat being measured was being lost to the universe, determine whether they could they distinguish between iron (s = 0.444 J/g · °C) and Ni (s = 0.449 J/g · °C). What is the percent difference between the specific heats of the two metals? Use the specific heat of iron as the theoretical value. % (b) Is this difference large enough to differentiate between the metals? Yes No This cannot be determined with the information...

SETR To determine the specific heat of an object, a student heats it to 100 C in boiling water. She then places the 50.1 g object in a 187 g aluminum calorimeter containing 105 g of water. The aluminum and water are initially at a temperature of 19.9 °C, and are thermally insulated from their surroundings. Part A If the final temperature is 22.4 C, what is the specific heat of the objed? Express your answer using two significant figures....

1) For part A, calculate q (the heat lost in calories) for copper and lead. The specific heats of these metals are in the background section. Then calculate q (the heat gained in calories) for the water in each case. Remember that you used 25.0 g of water in the experiment. Show your calculations 2)The heat lost by the metal and the heat gained by the water should be the same. Are they? If not, list possible sources of error....
