Here's a question for physics people out there. I have had a discussion at work today about whether the temperature in side a greenhouse is hotter than the outside temperature. My work colleague argued that the temp inside would never exceed the highest ambient outside temp on any one day, and that they only retain heat to keep the inside temp steadier.
I argued that they actually retain heat and so end up warmer than the outside temp and even exceed the peak temp on any particular day. I cannot find any documentation to support either point so I thought better refer it to the panel of experts that is IIS!!
I am certain I am right as the same effect should apply to cars and I know I have heard that cars can exceed 50deg C on some days, but again I have no documentation to prove it.
Plus my protagonist in all this is an annoying Kiwi and I need to prove him wrong!!
