Temperature can be measured using different scales. Complete the details for the missing temperatures in the table below:
| Temperature | Boiling point of liquid nitrogen | Melting point of lead |
|---|---|---|
| in ∘C^\circ\text{C}∘C | (i) | 327 |
| in Kelvin | 77 | (ii) |
A group of students measure the volume of a sample of gas at different temperatures while maintaining constant pressure in a laboratory experiment. The table below shows their results:
| Temperature in ∘C^\circ\text{C}∘C | Volume in litres |
|---|---|
| -60 | 1.065 |
| -20 | 1.550 |
| 20 | 1.465 |
| 60 | 1.665 |
| 100 | 1.865 |
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.
