Investigation: A beaker of hot water was left to cool in a room at 22 °C. Its temperature was recorded every 2 minutes.
Time (min): 0, 2, 4, 6, 8, 10
Temperature (°C): 80, 64, 52, 43, 37, 33
6.By how many degrees did the temperature fall in the first 2 minutes? What was the average rate of cooling in that time? (answer space)
7.By how many degrees did the water cool over the whole 10 minutes? (answer space)
8.Use interpolation to estimate the temperature at 5 minutes. (answer space)
9.Describe the trend in the data. (answer space)
10.If the investigation continued for a long time, what temperature would the water most likely settle at?- A0 °C
- Babout 22 °C (room temperature)
- C33 °C
- Dit would keep falling forever
