At zero °C temperature water (liquid) get starts to convert into its solid form (ice) and at 100°C temperature water (liquid) starts to change into water vapours. Between 0° to 100°C it remains in liquid state.
Thus,
(a) At 25°C, the water in Liquid state
(b) At 0°C, the water in Solid or/and liquid state (Transition state)
(c) At 100°C, the water in Liquid or/and gaseous state (Transition state)
Length (in hours) | Number of lamps |
|---|---|
300 − 400 | 14 |
400 − 500 | 56 |
500 − 600 | 60 |
600 − 700 | 86 |
700 − 800 | 74 |
800 − 900 | 62 |
900 − 1000 | 48 |
(i) Represent the given information with the help of a histogram.
(ii) How many lamps have a lifetime of more than 700 hours?
