Ответ:
Pressure will increase if temperature increase.
It would increase.
Ответ:
When the reaction in a calorimeter causes the temperature of the surrounding water to decrease, this means that the energy is absorbed during the course of reaction from water. The reaction is endothermic as it proceeded via the absorption of energy from the surrounding water present in the calorimeter. So, the energy(enthalpy) of products will be higher than the energy(enthalpy) of reactants.
