why is temperature of H2O2 measured in the graduated cylinder?
It would help if we knew what you were doing. Are you building a rocket ship? Dissolving blood with H2O2? Cleansing an open wound with H2O2? Washing the floor with it? Just what? As the question stands, I don't have the foggiest.
decomposition of H2O2 to water and O2
As the temperature increases the decomposition increases. Another way of saying it is that the rate of decomposition increases with increasing T.
