Consider two closed systems a and b. System a contains 3000 kj of thermal energy at 20c, whereas system b contains 200 kj of thermal energy at 50c. Now the systems are brought into contact with each other. Determine the direction of any heat transfer between the two systems.

Two systems A and B having different temperatures and energy contents are brought in contact. The direction of heat transfer has to be determined. Analysis of Heat transfer occurs from warmer to cooler objects. So, heat will be transferred from system B to system A until both systems reach the same temperature.
