Explain greenhouse energy balance

Paper 1, Paper 2 5 marks Difficulty 3

Infrared trapping fraction

In a second version of the same investigation, A simplified greenhouse model traps \(24\%\) of an incoming-equivalent \(1360\,\text{W m}^{-2}\) radiation stream. Calculate the trapped power per square metre. Use the diagram first, then calculate the requested value. Enter the numerical result and choose the interpretation that matches the physical meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
