I have a fairly basic (I hope) question - please note that the values given are just to make the problem easier to comprehend: Given: I'm heating, via convection, a constant sized spherical mass (Let's say m=1g) with a consistent surface area (Let's say SA = 1cm^2) at a constant temperature, Tc, (Let's say Tc = 60ºC) for a time, t = 60 minutes. Let us assume that the mass has an initial temperature (Ti) of 20ºC and after 60 minutes the temperature (Tf) of the mass will equal 50ºC. In a similar scenario (m=1g, SA=1cm^2, Ti=20ºC) how long will it take the mass to equal 50ºC if the new constant ambient temperature equals 100ºC? Experiment 1: m = 1g SA = 1cm^2 Ti = 20ºC Tc = 60ºC Tf = 50ºC t = 60 min Experiment 2: m = 1g SA = 1cm^2 Ti = 20ºC Tc = 100ºC Tf = 50ºC t = ?? min How would I figure this out? Assuming any necessary chemical or physical properties can be found for the mass. Any information would be greatly appreciated!
