1. Make a graph of temperature vs. time. Qla. What does the graph look like? Comment on the shape of the graph; include the reasons for the sudden drop in temperature after the first addition of ice, and why plateaus and temperature rise may occur.

Step 1
The temperature vs. time graph shows a non-linear cooling curve that starts at 33.4°C and decreases rapidly at first, then gradually slows down until it reaches an equilibrium temperature of about 18.6°C. Show more…

Use the graph below to answer the following questions: Changes in Global Temperature On the Y-axis, what does it represent? (Hint: this is where the graph starts and the graph is measuring change) What was the overall temperature change between 1850 and 2000? (calculate the actual difference) What trend does the data show between 1970 and 2000? (increase, decrease, staying the same) Use the graph below to answer the following questions: Changes in Temperature Note that the CO2 line has smaller ups and downs (it shows uniform fluctuations). What change/trend has occurred in CO2 concentration since 1960? Complete the following sentence: As CO2 concentration increases, temperature... If CO2 concentration continues to increase, what do you expect to happen to the temperature? (Infer from the trend shown in the graph)

Temperature The temperature of water in an ice cube tray is $70^{\circ} \mathrm{F}$ when it is placed in the freezer. Its temperature $n$ hours after being placed in the freezer is 20$\%$ less than 1 hour earlier. (a) Find a formula for the $n$ th term of the geometric sequence that gives the temperature of the water $n$ hours after it is placed in the freezer. (b) Find the temperatures of the water 6 hours and 12 hours after it is placed in the water. (c) Use a graphing utility to graph the sequence to approximate the time required for the water to freeze.
