ZZ Transform Method was introduced by Zain Ul Abadin Zafar [1] in 2016. In this paper, I have applied this new integral transform method for finding solutions to the problems occured on a principle Newton's Law of Cooling, which is an application of first order and first degree ordinary linear differential equation. ZZ Transform Method is similar to the other transforms such as Laplace and Sumudu Transforms. The advantagae of ZZ Transform Method is that it solves a differential equation with variable coefficients.
