You will need to generate a trendline for each portion of the cooling curve. In order to do this, you will need to identify which points to include in the cooling portion, and which points to include in the freezing portion For each cooling curve, Identify the lost temperature measurement to include in the cooling portion of the curves. Then generate a trendline each portion and record their slopes and y-intercepts in the table below Table 3. Freezing point determination (28pts) Determination of Freezing Points Use the data tables shown above to make two plots of cooling curves using graphing program. Each cooling curve is a plot of temperature (vertical axis) versus time (horizontal axis), and contains a cooling porting (when the liquid is cooling) and a freezing portion (when the liquid is turning to solid). You will need to generate a trendline for each portion of the cooling curve. In order to do this, you will need to identify which points to include in the cooling portion, and which points to include in the freezing portion For each cooling curve. identify the last temperature measurement to include in the cooling portion of the curves. Then generate a trendline each portion and record their slopes and y intercepts in the toble below. Table 3. Freezing point determination Table view List View Table 3.
