Relative humidity is indeed the ratio, usually expressed as a percentage, of the amount of water vapour currently in the air compared to the maximum amount of water vapour the air can hold at that specific temperature and pressure (its saturation capacity). Statement 2 is incorrect. When relative humidity is high, the air is already close to saturation, meaning it has little capacity to absorb more moisture. Therefore, evaporation from surfaces like skin is *reduced*, making it feel hotter and more uncomfortable. Statement 3 is correct. For a fixed amount of water vapour in the air, if the air temperature increases, the maximum amount of water vapour that air can hold also increases.
