(solution) Which of the following statements is not correct? A constant

  1. Which of the following statements is not correct?
    A constant pressure calorimeter is insulated to reduce the heat escaping to the surroundings
    A constant pressure calorimeter can be sealed to prevent vapour escaping from the system
    A constant pressure calorimeter can be calibrated so that the enthalpy of reaction can be easily determined
    A constant pressure calorimeter can be easily used to determine the enthalpy of reaction because the pressure is constant
