Solve the all parts of given problem:

Problem: A thermal insulated system containing aluminum beaker (100-g), water(150-g) and ice(50-g). The system's initial temperature is at 0 C. Then super heated steam at 120 C is guided into this system at a rate 2.5 g/sec for 15 seconds total.

Part I: find the final temperature of the system.

Part II: find the change of entropy of the system.

This is a physic problem, reply as soon as possible. Thank you.
