Propylene glycol specific heat capacity
WebbThe Food and Drug Administration (FDA) has classified propylene glycol as an additive that is “generally recognized as safe” for use in food. It is used to absorb extra water and maintain moisture in certain medicines, cosmetics, or food products. It is a solvent for food colors and flavors, and in the paint and plastics industries. Webbat temperature 70°C, it shows that specific heat capacity of 8ml of ethylene glycol mix with the water has the highest specific heat capacity which is 13.2130 J/g*°C. The lowest specific heat capacity obtained was the mixture of 8ml of ethylene glycol and 12ml of ultrapure water. In this experiment, the specific heat capacity was
