Insolation (calorimeter)

[Emiliano Olivo Cauberghs]

Hi,
Dr.Lavelle mentioned in his previous lecture that a calorimeter needs to be "insulated" in order to measure the temperature changes and used the example of a polyester cup. I am still a bit unsure of what insulated really means and how it is necessary for a calorimeter. An example would be great.
Thanks in advance.

Hi. So the calorimeter is insulated because neither the heat nor matter can exchange with the surroundings. Example of isolated system besides calorimeter is hydroflask which keep your water cold/hot for a long time, so there is no heat or matter exchange.

Calorimeters help reduce the heat exchange in different substances.The calorimeters also uses the process of measuring the heat of chemical reactions or physical changes.

If something is insulated, there is no influence from outside temperatures on whatever is inside the system. A common example of an insulator is a thermos, which keeps food/drinks cold or hot since neither heat or matter can exit or enter the system. This is an essential quality for calorimeters to help minimize any changes in temperature.

Insulation isolates the system from the surroundings, and is used in an isolated system.
