As part of his science project, Prithvi was supposed to record the temperature every hour one Saturday from 6 am to midnight. At noon, he was taking lunch and forgot to record the temperature. At 8:00 pm, his favourite show came on and so forgot again. He recorded the data so collected on a graph sheet as shown below.
- Why does it make sense to connect the points in this situation?
- Describe the overall trend, or pattern, in the way the temperature changes over the time period shown on the graph.
- Estimate the temperature at noon and 8 pm.
उत्तर
- By connecting the points, it is easier to understand a change in the temperature.
- Initially the temperature was 8°C at 6 am and started increasing strictly till 1 pm and after that it decreased to 8°C till 12 pm.
- At 12 pm 19°C and at 8 pm 10°C.
