How do chemicals from plastic cups leach into hot tea?
Chemicals from plastic cups can leach into hot tea through a process known as thermal degradation. When plastic is exposed to heat, the molecular bonds that hold it together can break down, releasing chemicals into the surrounding liquid. This process can be accelerated by the high temperatures of hot tea, which can cause the plastic to become more permeable and allow chemicals to escape. Additionally, the acidity of the tea can also contribute to the leaching of chemicals, as acidic liquids can break down the plastic more easily than neutral or alkaline liquids.
The rate and extent of chemical leaching from plastic cups into hot tea can depend on various factors, including the type of plastic used, the temperature of the tea, and the duration of time that the tea is in contact with the plastic.
