To determine the measure of heat released or absorbed during a physical or chemical process, a calorimeter is used. The technique employed in a calorimeter is based on two fundamental laws: the first law of thermodynamics and the second law of thermodynamics.
The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transferred or transformed from one form to another. This law is often summarized as "energy in equals energy out." In the context of a calorimeter, it means that the heat released or absorbed during a process can be determined by measuring the changes in energy within the system.
The second law of thermodynamics relates to the direction of heat flow. It states that heat naturally flows from a region of higher temperature to a region of lower temperature, until both regions reach thermal equilibrium. This law is often summarized as "heat flows from hot to cold." In the context of a calorimeter, it means that the heat released or absorbed during a process can be measured by monitoring the temperature changes in the system.
Considering the given options, the correct choice for the two fundamental laws employed in a calorimeter technique is Option 2) B: first law of thermodynamics and second law of thermodynamics.
