True or false 1. Energy of the universe will not change 2. Entropy of the system will always be positive 3. Entropy of the surrounding will always be positive 4. Entropy of the universe will be conserved 5. Entropy of the system being positive


Let's analyze each statement: 1. **Energy of the universe will not change**: **True**. According to the law of conservation of energy, the total energy in an isolated system (like the universe) remains constant; energy can only change forms. 2. **Entropy of the system will always be positive**: **False**. While it’s common for entropy to increase in a closed system due to natural processes tending toward disorder, there can be processes that decrease the entropy of a specific system, although they may require external work and generally do not apply to isolated systems. 3. **Entropy of the surroundings will always be positive**: **False**. Similar to the previous statement, while the entropy of the surroundings often increases in spontaneous processes, it is possible for it to decrease in certain contexts, particularly when considering the overall energy exchanges with the system, especially when energy is transferred in a way that cools the surroundings. 4. **Entropy of the universe will be conserved**: **False**. The second law of thermodynamics states that the total entropy of the universe increases over time for spontaneous processes. 5. **Entropy of the system being positive**: **False**. The entropy change of a system can be negative in processes where the system becomes more ordered, or in processes that absorb energy from the surroundings. In summary: 1. True 2. False 3. False 4. False 5. False
