If a mass of moist air contained in a closed metallic vessel is heated, then its
Relative humidity decrease
In a rigid sealed vessel without liquid water, vapour mass and dry-air mass remain constant, so humidity ratio is unchanged. Vapour partial pressure increases in proportion to absolute temperature, while saturation pressure increases much faster over ordinary moist-air temperatures. Thus relative humidity decreases.
