water. Dissolving plastic has found several surprising uses. The textile industry uses PVA thread to make “open weave” fabrics. PVA thread is substituted for some of the ordinary threads when the fabric is woven. Upon washing in hot water the PVA thread dissolves, leaving an open structure nearly impossible to achieve directly. However, in most
The reason why sugar dissolves at a faster rate in hot water has to do with increased molecular motion.
