Question

what does "using a calorimeter to measure changes in heat and determine the enthalpy change for a chemical process" mean?

Answer 1

Answer:

Calorimetry measures enthalpy changes during chemical processes, where the magnitude of the temperature change depends on the amount of heat released or absorbed and on the heat capacity of the system.

Answer 2

Here is your answer:

What does "using a calorimeter to measure changes in heat and determine the enthalpy change for a chemical process" mean?Generally, calorimetry refers to an experimental technique that we use for the measurement of enthalpy( delta H) and internal energy( delta U). Calorimetry techniques use the principle of thermometric methods carried out in a vessel. This is the calorimeter that we keep immersed in a specific volume of liquid.

We calculate the heat let out in the process with the help of known heat capacities of the liquid and the calorimeter. This, we can do by measuring the temperature differences. There are two different conditions under which we can make these measurements. They are:

At constant pressure, qp

At constant volume, qv

In other words:

Calorimetry measures enthalpy changes during chemical processes, where the magnitude of the temperature change depends on the amount of heat released or absorbed and on the heat capacity of the system.
