Consider two closed systems A and B. System A contains 3000 kJ of thermal energy at 20°C, whereas system B contains 200 kJ of thermal energy at 50°C. Determine the direction of any heat transfer between the two systems.
Understand the Problem
The question is asking us to analyze two closed systems with given thermal energy and temperatures and to determine the direction of heat transfer between them when they are brought into contact. The analysis indicates that heat will flow from the warmer system to the cooler one until both reach the same temperature.
Answer
Heat transfers from system B to system A.
Heat will be transferred from system B to system A until both systems reach the same temperature.
Answer for screen readers
Heat will be transferred from system B to system A until both systems reach the same temperature.
More Information
Heat transfer naturally occurs from objects at a higher temperature to those at a lower temperature to reach thermal equilibrium.
Tips
A common mistake is focusing solely on the quantity of energy rather than temperature differences.
