A sample of gas is placed in a temperature-controlled chamber in a laboratory. The gas is taken through two stages.
| Measurement | Temperature information |
|---|---|
| Starting temperature | −62 ∘C-62\,^\circ\text{C}−62∘C |
| Stage 1 | temperature rises by 47 K |
| Stage 2 | temperature falls by 19 ∘C19\,^\circ\text{C}19∘C |
Calculate the temperature of the gas after stage 2, in kelvin.
