When soggy biscuits are kept inside the fridge for sometime they becom...
Explanation:
Introduction:
When soggy biscuits are kept inside the fridge for some time, they become crisp. This change in texture occurs due to the low humidity inside the fridge, which causes the biscuits to release their excess moisture and become crisp.
Low Humidity:
Inside the fridge, the humidity is relatively low compared to the surrounding environment. The low humidity creates a drier environment, which facilitates the evaporation of moisture from the biscuits. As a result, the excess moisture present in the soggy biscuits is gradually released into the surrounding air.
Moisture Absorption:
As the biscuits release moisture, the dry air inside the fridge absorbs it. The air acts as a desiccant, absorbing the extra moisture from the biscuits and creating a drier environment. This absorption process helps in reducing the moisture content in the biscuits, leading to their crispness.
Comparison with High Humidity:
If the humidity inside the fridge were high, the extra moisture released by the biscuits would not be absorbed effectively. In such a scenario, the biscuits would remain soggy, as the surrounding air would already be saturated with moisture and unable to absorb more.
Effects of Cooling:
Although cooling does not directly cause the biscuits to become crisp, it plays an indirect role. When the biscuits are placed inside the fridge, the cooling effect causes the moisture inside them to condense and form droplets. This condensation makes the biscuits appear and feel soggy. However, as the biscuits gradually reach the temperature equilibrium with the surrounding environment, the excess moisture is released, leading to crispness.
Conclusion:
In conclusion, when soggy biscuits are kept inside the fridge for some time, they become crisp due to the low humidity inside. The low humidity facilitates the release of excess moisture from the biscuits, which is then absorbed by the dry air inside the fridge. This process helps in reducing the moisture content of the biscuits, resulting in their crisp texture.
