A weather-monitoring instrument is tested in a chamber. The instrument absorbs 18 J of energy by radiation each second at each temperature shown. Other energy transfers are negligible.
The instrument is initially at −10 ∘C-10\ ^\circ\text{C}−10 ∘C.
| Temperature of instrument in ∘C^\circ\text{C}∘C | Energy emitted by radiation each second in J |
|---|---|
| -10 | 14 |
| 0 | 16 |
| 10 | 18 |
Explain what happens to the temperature of the instrument. Include the final steady temperature in your answer.
