Objects A and B, isolated from the environment, are initially separated from each other and are then placed in thermal contact. Their initial temperatures are TA=0°C and TB=100°C. The heat capacity of B is twice the one of A. After a certain time, the system reaches equilibrium. The final temperatures are:
a) TA=TB=50°C.
b) TA=TB>50°C.
c) TA=TB<50°C.
d) TA>TB>50°C.
e) TA>50°C>TB.
