Abstract
Plasma activated water (PAW) produced by the interaction of non-thermal plasma (Gliding arc air plasma) and water contains reactive species specifically oxygen and nitrogen species (RONS) such as nitrates (NO3 -) and nitrites (NO2- ), hydrogen peroxide (H202) and short-lived radicals such as hydroxyl radicals (OH) and nitric oxide (NO). PAW poses many biological applications which have been confirmed as directly related to the chemistry and concentration of RONS. The studies analysing properties of plasma activated water have been focused on chemical properties of PAW. A very recent study observed the unique washability property of plasma activated water which could not be explained by the presence of ROS and RNS. They proposed plasma activation can bring about changes to the thermodynamic property (surface tension) of water and that the washability property exhibited by plasma water can be attributed to that. The objective of this present study is to investigate the physical properties of plasma activated water, specifically the thermodynamic (surface tension) and transport (viscosity) properties of plasma activated water and learn of the changes brought to these properties of water by plasma activation. The result of the study makes it clear that the plasma activation brings about significant changes to thermodynamic and transport properties of water.
