Experimental Procedure

Here's how to carry out the experiment and analyze the results: Step 1: Experimental Procedure a)* Use the measuring cylinder to measure 100 \, cm^3 of water and transfer it into Beaker A. b)* Pour another 100 \, cm^3 of water into Beaker B. c)* Read and record the initial temperature, _0, of the water in Beaker B using a thermometer. d)* Attach a thread to the pendulum bob and immerse the bob into the water in Beaker A. e)* Place Beaker A on a tripod stand with a source of heat underneath. Heat the water in Beaker A for 3 minutes. f)* Immediately after disconnecting the heat source, read and record the temperature, , of the water in Beaker A. g)* Quickly transfer the hot pendulum bob from Beaker A into the water in Beaker B. h)* Stir the water in Beaker B continuously with a stirrer until a uniform final temperature, _f, is reached. i)* Read and record the final temperature, _f. j)* Dispose of the water in both beakers. k)* Repeat the entire procedure (steps a-j) for water volumes V = 150, 200, 250, and 300 \, cm^3. In each case, ensure the same volume of water is used in both Beaker A and Beaker B for a given trial. Step 2: Calculations For each set of readings (each volume V), evaluate the following quantities: P = ( - _0) Q = (_f - _0) Step 3: Tabulation of Results Record your measurements and calculated values in a table like the one below: | Volume V (cm^3) | Initial Temp. of B, _0 (^) | Final Temp. of A, (^) | Final Mixed Temp., _f (^) | P = ( - _0) (^) | Q = (_f - _0) (^) | | :------------------------ | :----------------------------------------------- | :------------------------------------------- | :--------------------------------------------- | :------------------------------------------ | :------------------------------------------ | | 100 | | | | | | | 150 | | | | | | | 200 | | | | | | | 250 | | | | | | | 300 | | | | | | Step 4: Graphing and Slope Determination Plot a graph with P on the vertical axis and Q on the horizontal axis. Draw the best-fit straight line through the plotted points. Determine the slope, s, of this line. Choose two distinct points (Q_1, P_1) and (Q_2, P_2) on your best-fit line and calculate the slope: s = (P_2 - P_1)/(Q_2 - Q_1) Step 5: Precautions To ensure accurate results: Minimize heat loss to the surroundings by performing the experiment quickly and using insulating materials if available. Ensure the pendulum bob is transferred as quickly as possible from Beaker A to Beaker B to prevent heat loss to the air during transfer. That's 2 down. 3 left today — send the next one.
