The table shows average radiation intensities for two model planets. Each value is averaged over the whole surface.
| Planet | Incoming solar intensity in W/m2\mathrm{W/m^2}W/m2 | Reflected solar intensity in W/m2\mathrm{W/m^2}W/m2 | Outgoing emitted intensity in W/m2\mathrm{W/m^2}W/m2 |
|---|---|---|---|
| P | 400 | 120 | 270 |
| Q | 360 | 60 | 310 |
Which describes their temperature changes?
P warms and Q warms.
P cools and Q cools.
P cools and Q warms.
