Matlab

Consider a hot metal ball dropped into cold oil (known as quenching). Assume the heat is transferred by convection only, and the ball is small enough that its temperature is going to be uniform throughout the quenching process. The process can be modeled as: hA(T_infinity -T) = rhoVC_p dT/dt Where rho = 2.7xl0^3 kg/m^3 is the density of the metal ball, Cp = 0.9J/(gm . K) is the specific heats for the metal ball, r=10 cm is the radius of the metal ball. h=2000 W/(m^2K) is the convective heat transfer coefficient of water. If the hot metal ball has an initial temperature of 1200K, and eventually cools down to 30 OK, Use ode45() to solve and find out the temperature after 1 min,
