To sterilize a 50.0-g glass baby bottle, we must raise its temperature from 22.0ºc to 95.0ºc . how much heat transfer is required?

To sterilize the said baby bottle we have to raise the temperature from 22.0 degrees Celsius to 65 degrees Celsius and in order to determine the amount of heat that has to be supplied, we need the heat that would be absorbed by the baby bottle. First, we need to know the material of that baby bottle which, for this case, is made up of glass since we need the specific heat capacity of the material wherein for glass it is equal to 0.84 J / g C. We determine the heat as follows:

Heat absorbed = Heat to be supplied = Heat transferred m C (T2 - T1)
Heat transferred = 50.0 g (0.84 J/ g C) (95 C - 22 C) = 3066 J

Olá. porque a reação na temperatura é muito rapida a do copo : )
