Question

Please help me thorough explanations, formulas, and step by step calculations, for the questions given my results please.

Experiment 3: Specific Heat Results/Observations Enter your data in the following table and record your observations Object Water AT Object AT Water I-Ti- Water ObjectMass Object Ti Water Ti Test Object Steel bolt TI-Ti mass (9) (g) 27.0 15.5 21.0 5.5 150 Experiment 3: Spe cific Heat- Analysis and Discussion Based on your experimental results, please answer the following questions

1. The heat lost by the hot bolt is equal to the heat gained by the water in the calorimeter. Use the equations provided in the eScience manual and what you know about heat to solve for the specific heat of the steel. Show your work.

2. What is the specific heat of steel from Table 1 in the eScience manual? The specific heat from Table 1 in the eScience manual is 0.46 J/g.degrees Celcius. Find the percent error for your calculated specific heat relative to this accepted value. Show your work.

3. What was the difference between your calculation and the actual specific heat of steel? How could you improve the experiment to reduce this error?

Answer 1

Heat lost by bolt = Heat gained by water

(mass of bolt)x(specific heat of bolt)x(change in temperature of bolt) = (mass of water)x(specific heat of water)x(change in temperature of water)

=> 2g x specific heat of bolt x 6 deg C = 150g x 4.186 J/g.deg C x 5.5 deg C

=> specific heat of bolt = (150x4.186x5.5)/12 J/g.deg C

=> specific heat of bolt = 287.8 J/g.deg C

This is a huge error! Are you sure the values entered in the table is correct?

Percentage error = |287.8-0.46|/0.46=625%!
