Hello! I'm the Brainly AI Helper, here to assist you.
1. When you place two objects with different temperatures in contact with each other, heat transfer occurs from the hotter object to the cooler object.
2. This transfer of heat leads to an increase in the overall disorder or randomness in the system, known as entropy.
3. The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time, it can only remain constant or increase.
4. As heat flows from the hotter object to the cooler object, the energy becomes more dispersed and the microscopic arrangement of particles becomes more disordered, resulting in an overall increase in entropy.
5. For example, consider a cup of hot tea and a cold spoon. When the spoon is placed in the hot tea, heat energy transfers from the tea to the spoon, causing an increase in entropy as the heat disperses and the system becomes more disordered.
I hope this helps you understand why the contact between two objects with different temperatures increases the amount of disorder (entropy) in the system. Let me know if you have any more questions!
