1. A piece of material with a mass m and a specific heat at constant pressure given by c, = a + bT, where T is the temperature and a and b are constants, is initially at a temperature T. It is brought into contact with a heat reservoir at temperature T2, where T2 > T1, which brings the mass to a final temperature of T2. a) What is the change in entropy of the mass? b) What is the change in entropy of the reservoir?

1. A piece of material with a mass m and a specific heat at constant pressure
given by c, = a+bT, where T is the temperature and a and b are constants, is
initially at a temperature T1. It is brought into contact with a heat reservoir at
temperature T2, where T, > T1, which brings the mass to a final temperature
of T2.
a) What is the change in entropy of the mass?
b) What is the change in entropy of the reservoir?
