humidity conditions
1Humidity — is the amount of water vapor in the air. In daily language the term humidity is normally taken to mean relative humidity. Relative humidity is defined as the ratio of the partial pressure of water vapor in a parcel of air to the saturated vapor… …
2Humidity buffering — refers to the ability of materials to moderate changes in relative humidity by absorbing and desorbing water vapour from surrounding air. This is also referred to as moisture buffering.The phenomenon has long been exploited for preserving items… …

4Relative humidity — is a measurement of the amount of water vapor that exists in a gaseous mixture of air and water. Estimating relative humidity The relative humidity of an air water vapor mixture can be estimated if both the temperature ( T ) and the dew point… …
5Standard conditions for temperature and pressure — Not to be confused with Standard state. In chemistry, standard condition for temperature and pressure (informally abbreviated as STP) are standard sets of conditions for experimental measurements, to allow comparisons to be made between different …
