It is difficult to burn a wet piece of wood because water present in it, keeps the temperature of wood below its ignition temperature..
and as we know, for a substance to catch fire..it is needed to heat it to its ignition temperature.
So, it is difficult to burn a wet piece of wood.

Solar Constant is the rate at which energy reaches the earth's surface from the sun, usually taken to be 1,388 watts per square metre.

Hey Buddy !☺
It is difficult tO burn a wet piece of wood because the water present of thE wet piece of wood absorbs the heat which is supplied to burn the wood thus, prevents wood from bUrning easily.
The amount of sun energy falling on a unit square area per second is called the Solar Constant.
