In a closed system, the energy that is added can lead to various effects depending on the form of energy introduced. Here's a breakdown of the statements:
1. **It does work or increases thermal energy**: This statement is generally true. When energy is added to a closed system, it can either do work on the system (for example, through mechanical means) or increase the internal energy of the system, which typically manifests as an increase in thermal energy (temperature) if the added energy is in the form of heat.
2. **It is converted to radiation**: This statement can be somewhat misleading. While energy can be converted to radiation, particularly if the system reaches a high enough temperature (where it emits thermal radiation), it is not an inherent outcome of simply adding energy to a closed system. The conversion to radiation depends on the specific circumstances within the system.
3. **It cannot heat the environment**: This statement is false for a closed system. Though the system itself is closed concerning matter exchange, if energy is added in the form of heat, it can increase the temperature of the system, and if the system's boundaries allow for some form of thermal radiation or other forms of energy transfer, it could potentially affect the surrounding environment.
In summary, the first statement is the most universally accurate concerning energy added to a closed system, while the second depends on conditions, and the third is false as a general principle.
