If you are piling cups of the same size, then it will efficiently double the thickness of the isolating walls. Think of this as amplifying the thickness of the insulation to preserve the heat inside the cups from evading. When you measure the heat of the reaction, you want to arrest all of the heat from the reaction. A calorimeter does this by measure the alteration in temperature of the solution or gas round the reaction and then calculates the heat that was generate by using the specific heat of the liquid, typically water, or the gas.
The calorimeter is designed by using two cups stacked one over the other in order to minimize the heat loss from the calorimeter.
Further Explanation:
A calorimeter works on the principle of conservation of the energy. When two or more different entities are mixed at different temperature, the exchange of heat takes place between the two entities.
In order to make the proper measurements of the heat exchange taking place in the system, the system is supposed to be considered as a completely isolated system and it does not loss any heat to the outer surrounding. It is also considered that the calorimeter also does not absorb any heat.
Therefore, in order to ensure that there is no loss of heat to the environment, the calorimeter should be very well insulated and the use of two cups stacked one over the other increases the width of the calorimeter and therefore, reduces the loss of heat.
Thus, the calorimeter is designed by using two cups stacked one over the other in order to minimize the heat loss from the calorimeter.
