Similarly, water in a narrow tube rises or falls when its temperature rises or falls. This is the working principle of every sealed, liquid-containing thermometer. However, if something as abundant and cheap as water works so well, why do we insist on snubbing it for something as extremely ...
Why does water boil at a higher temp then NH_3 when they are both dipoles? Suggest why the melting temperature of magnesium oxide is higher than that of magnesium chloride, even though both are almost 100% ionic. What does the conductivity of a material depend on?
Why does raising the temperature cause a liquid to boil? Why does decreasing the temperature of a liquid make it freeze? Why do liquids evaporate at different rates? Why does ice float in liquid water? Why does increasing the temperature of a solid make it melt?
Slow-moving water carries too little energy to move larger sediment, and instead will carry fine sands and silts. Here, the streams sorted the sediment in a way that left behind exclusively coarse sand and gravel behind. Glacial till is a whole different creature. It’s deposited by the ...
Learn why betta fish don’t belong in small, one-gallon tanks. There are better options if you want your fish to be happy and healthy.
It was based on an interplay of contrasts, um, different temperatures, or hard and soft textures. Sometimes meat was only partially defrosted. For example, one way of preparing meat was to boil it briefly, leaving the center frozen. So cooked food, or partially cooked food, for ancient Arc...
here's where we need to look beyond obvious factors and consider things like culinary preferences.Although the diet of ancient Arctic people mainly consisted of raw and minimally cooked food, it was carefully prepared.It was based on an interplay of contrasts—uh, different temperatures … or har...
try to clean it with water and a rag; and, if the grime is stuck and you need a little help cleaning up, use liberally-applied salt as a scouring powder to remove the bits and bobs. If you really need some assistance, put water into the pan, boil the water on the stove, and the...
