moisture is presence of small amount of liquid in substance (especially water).

 

humidity is nothing but water vapor holding capacity of air. i.e when we say 60% humidity ,the air contain 60% vapor of its capacity and if there is 100% humidity the air can't take any more water vapor. hence when you will sweat in 100% humid air the sweat will not evaporate becaues air will not be able to take any more vapor .

you know when you are in AC room your body sweat's but sweat evaporation rate and sweating rate is same hence you fell cool and you don't understand that you are sweating.

 

relative humidity is the amount of water vapor in the air at a specific temperature compared to the maximum water vapor that the air is able to hold
