Why does plastic take longer to dry than ceramic or glass?

1. Different thermal conductance, which affects the evaporation rate of the water.

2. Perhaps the glass or ceramic has a smoother surface - so less water

adheres to the surface to need evaporating?

3. Plastic holds a static charge better....

so it could be there's some bonding going on between the water and the plastic . Water forms larger droplets on plastic so there would be less surface area to volume.

I think it's because plastic's evil. I never did switch over to plastic cutting boards and it turned out I was right. Plastic holds more bacteria than wood surfaces.

Plastic bad. Wood, glass, ceramic good.

4. Ceramic and glass are denser

So they have more mass for the same size and thickness plate. They contain more heat than the plastic plates, so they take longer to cool off. Therefore, they pump more heat into the water droplets, making them evaporate faster.

Also consider that glass and ceramic are often thicker than plastic, so they have both more volume and more mass per volume. So there's a lot more mass to retain heat.

Fired clay has a density of 1.3, glass has a density of about 2.4, and high-density polyethylene is 0.95 or so.

5. My computer refuses to start... Please help...

That is a stupid question. So is yours. Some details might yield a legitimate and helpful response.
