PLEASE I NEED THIS IM BEING TIMED construct a graph of temperature versus time. Put temperature on the y-axis and time on the x-axis. Graph all three sets of data on the same graph. Use a different colored pencil for each test material. Provide a key on the graph relating the pencil color to the test material. Calculate the change in temperature from start to finish for the air and each of the samples and record on your data sheet. Which water sample lost the least amount of heat energy over the 6-minute time interval? Was the rate of heat loss constant during each experiment? How can you tell? Which material was the best insulator? Which material was the least effective insulator? Write a summary paragraph discussing this experiment and the results. Summarize the conclusions that you can draw from this experiment. Explain why the design of the bird's nest provides good insulation for the eggs. For the control, and each test sample, you will be measuring the amount of heat lost by the water in the calorimeter over 6 minutes, taking the temperature every 30 seconds. Be sure to record your data on your data sheet .

Calculate: select the worksheet tab. this tab you calculate the analyte concentration. ď‚· fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.) ď‚· record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes. ď‚· record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
