Why is it that sponges hold more cold water rater than hot?

Sponges hold more cold water than hot water primarily due to the viscosity of the liquids. Cold water is denser and has higher viscosity, allowing it to fill the porous structure of the sponge more effectively. In contrast, hot water has lower viscosity and may evaporate more quickly, reducing the amount that the sponge can retain. Additionally, the thermal expansion of water means that as water heats up, it occupies a larger volume, which can also affect the sponge's capacity to hold it.
