Air is compressed in a piston–cylinder device from 90 kpa and 20°c to 650 kpa in a reversible isothermal process. determine the entropy change of air. the gas constant of air is r = 0.287 kj/kg·k. (you must provide an answer before moving on to the next part.)

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
