Q1: If a calorimeter is not assumed to be adiabatic, how would one calculate the heat transfer? Guide Questions: What are the parameters to be considered and the equations to be used? What law of thermodynamics does this transfer of heat to the surroundings touch? Is an adiabatic system automatically considered as a closed system? Please help me understand by also attaching a reference/book/journal article. This would help me in my essay. Thank you.
