1. The problem statement, all variables and given/known data Modelling the following equation: k = Delta Q / t 2. Relevant equations Q = T2 - T1 = -40 (fixed) t = Delta Q / k. I need to find t. k can be floating so I suppose 0 to 10 minutes with 0.5 increments 3. The attempt at a solution I don't have MATLAB on me at the moment, but I think I should just set a loop for k, nest the expression for t and the plot a k vs t curve. Does that sound right?
