Temperature can be measured using different scales. Complete the details for the missing temperatures in the table below:
| Temperature | Boiling point of liquid oxygen | Boiling point of water |
|---|---|---|
| in ∘C^\circ\text{C}∘C | (i) | 100 |
| in Kelvin | 90 | (ii) |
Some students measure the volume of a sample of gas at different temperatures while maintaining constant pressure. The table below shows their results:
| Temperature in ∘C^\circ\text{C}∘C | Volume in litres |
|---|---|
| -40 | 0.93 |
| 20 | 0.85 |
| 40 | 1.25 |
| 80 | 1.41 |
| 120 | 1.57 |
Identify the coordinates of the anomalous point from the table.
Use the non-anomalous data points to find the temperature (in ∘C^\circ\text{C}∘C) at which the volume of the gas would theoretically become zero.
