Question: 1 / 400

What is required to avoid overheating when drying a sample?

The sample must remain still

The sample must be frequently stirred

To avoid overheating when drying a sample, frequent stirring is essential. This action promotes even heat distribution throughout the sample, preventing localized overheating which could lead to degradation or alteration of the material properties. When a sample remains static, certain areas may absorb heat more than others, increasing the risk of overheating in those spots. Stirring helps maintain a uniform temperature across the sample, which is crucial in processes where precise moisture content is necessary.

Using a high heat setting is counterproductive as it can significantly raise the temperature of the sample, increasing the likelihood of damage. Additionally, minimizing drying time without proper control can lead to uneven drying and overheating as well. Therefore, the practice of frequently stirring the sample provides the necessary control over the drying process, ensuring that it progresses safely and effectively.
