WebNext, we add our two solutions to our calorimeter which has made of two coffee cups. And since the top coffee cup is loose fitting, this reaction is under the constant pressure of the atmosphere. So this is constant pressure calorimetry. After the two aqueous solutions mix, the reaction occurs and we watch the thermometer in the calorimeter. curly hair shampoo for men
