Question

Why our back get wet or moist when we sit on lawn even if it is completely dry? may i know the reason?

Answer 1

Not very nice I know, but maybe sweat?

Answer 2

The lawn may be dry to the touch, but what about the soil underneath?  The soil moisture is either wicking up into your clothes or as the person above mentioned, sweat.......you are in contact with a very humid environment and by be sweating.  Plants give off moisture when their leaf pores are open and you've trapped that moisture with your body.
