A glass sheet is cooling after being manufactured. A sensor records the energy emitted as infrared radiation from the same area of the glass sheet at two temperatures.
| Temperature of glass sheet in °C | Time interval in s | Energy emitted in J |
|---|---|---|
| 160 | 10 | 140 |
| 220 | 12 | 270 |
Calculate the energy emitted each second at each temperature. Use your answers to explain how the temperature affects the rate at which the glass sheet emits infrared radiation.
