5 Questions
What is the relation between enthalpy change and temperature change?
$\Delta H = q_p = mC_p \Delta T = VdC_p \Delta T$
Why are metallic calorimeters not used for measuring thermochemical changes?
Metals may react with substances
What is the purpose of determining the calorimeter constant?
To account for heat absorbed by calorimeter, thermometer, and stirrer
How is the calorimeter constant for a glass vessel determined?
Using the method of mixtures with hot water at a specified temperature
Why is only the area of the calorimeter in contact with the liquid considered for absorbing maximum heat?
When thermal conductivity of the material of calorimeter is low
