DEMONSTRATE THE DIFFERENCES IN TEMPERATURE DENSITY, THROUGH A FUN EXPERIMENT. CAITLIN: TODAY WE ARE TESTING CONVECTION USING COLD WATER OR AN ICE CUBE DIED BLUE. WARM OR HOT WATER DYED RED AND ROOM ...

Supercooled water may be a two-for-one deal. A long-standing theory holds that liquid water at temperatures well below freezing is composed of two different arrangements of molecules, one with high ...

This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

In physics, chilling out isn’t as simple as it seems. A hot object can cool more quickly than a warm one, a new study finds. When chilled, a warmer system cooled off in less time than it took a cooler ...

Decades after a Tanzanian teenager initiated study of the “Mpemba effect,” the effort to confirm or refute it is leading physicists toward new theories about how substances relax to equilibrium. It ...

WXMI — In our science experiment today, we look at a disappearing coin trick, which really is no trick at all. It illustrates density and refraction. Some things are more dense (or heavier) than other ...

The story goes that in 1963, Tanzanian high school student Erasto Mpemba was making ice cream with his class when he impatiently put his sugar and milk concoction into the ice cream churner when it ...

It sounds like one of the easiest experiments possible: Take two cups of water: one hot, one cold. Place both in a freezer and note which one freezes first. Common sense suggests that the colder water ...

A long time series of data simulated by the NCAR Community Climate Model is used to empirically determine the effects of imperfect spatial and temporal sampling on estimates of the model's global-mean ...
