Temperature, Humidity and MKT in stability studies

Temperature, Humidity and MKT in stability studies:

*Relative humidity is a measure of how close the air is to reaching saturation with moisture

*Saturation is the point when the air can hold no more water vapor and is essentially full.

*Let us take  a glass filled with wine half full.

     The glass can hold 200 mL

*100 mL wine is in the glass - Absolute

*Content in % is 50 - Relative

Mean kinetic temperature :

*Across the year, temperatures vary from zero to 40°C

*The mean kinetic temperature will be the climatic condition.

*It is somewhat similar to average, But not exactly.

*It was calculated by using Arrhenius equation.

*For example, INDIA climate: 30°C / 75%RH.

*when Air becomes warm, Warm air can hold more moisture, because air expands

Relative humidity decreases.

*Air becomes cool, Relative humidity increases
