An immersion heater can be safely placed in a metal container, as long as the metal is non-corrosive and can withstand the heat generated by the heater. However, it is not safe to place an immersion heater in a plastic container, as the heat can cause the plastic to melt or release harmful chemicals. It is important to always check the manufacturer's guidelines and recommendations for the specific immersion heater being used to ensure safe and proper usage. **

To remove melted plastic from a ceramic glass cooktop, start by turning off the cooktop and allowing it to cool completely. Once it's cool, use a plastic scraper or a credit card to gently scrape off as much of the melted plastic as possible. Then, apply a small amount of ceramic cooktop cleaner to the affected area and use a soft cloth to gently scrub away any remaining residue. Finally, wipe the cooktop clean with a damp cloth and dry it thoroughly. Avoid using abrasive materials or harsh chemicals, as they can damage the cooktop surface. **

Global behavior refers to the overall behavior or pattern of a system over a long period of time, while boundary behavior refers to the behavior of a system near its boundaries or limits. In the context of a mathematical function or system, global behavior may describe the overall trend or shape of the function, while boundary behavior may describe how the function behaves as it approaches certain limits or boundaries, such as approaching infinity or approaching zero. Understanding both the global and boundary behavior of a system is important for analyzing and predicting its behavior in different scenarios. **

Monotonic behavior refers to the consistent increase or decrease of a function without any fluctuations or reversals in direction. It focuses on the trend of the function over a specific interval. On the other hand, global behavior looks at the overall characteristics of a function across its entire domain, including features such as asymptotes, end behavior, and overall shape. Global behavior provides a more comprehensive understanding of how the function behaves as a whole, while monotonic behavior focuses on the trend within a specific interval. **
