Unformatted text preview: similar way, if we focus on the cool down period where no mechanical work is performed, the heat balance simplifies to ) ( lab cal T T H dt dT cm = (8) Which can be further arranged to provide a simple first order differential equation: lab cal HT HT dt dT cm = + (9) or lab T T dt dT = + (10) where the time constant H cm cal = (11) Note that the specific heat of aluminum is c = 0.900 Joules / gram C and the mass of the calorimeter is 205 grams. 9 of 9...
