It does have one use in cooking: Homemade ice cream recipes often instruct you to sprinkle rock salt on the ice surrounding the cylinder filled with the ice cream mixture. Salt makes ice melt faster, and the resulting salt and water mix freezes at a lower temperature than ice alone. This...
Sodium metal is soft whereas sodium chloride is very hard. Explain why. Why does decomposed aspirin melt faster? Explain why ionic solids are generally considered harder than most molecular solids. Why do you think metals usually have higher densities than other materials?
Why does ice melt faster in water? What characteristics make water vapor the most effective absorber of infrared radiation in the atmosphere? Why is the mesosphere the coldest layer? Why is ionizing radiation higher at plane altitudes? What causes color change in chemical r...
Why does copper not react with water or steam? Copper: Copper is one of Earth's elements. It is identified on the periodic table of elements with the atomic symbol 'Cu' and the atomic number '29.' The word 'copper' is derived from the Latin wordcuprumwhich is why its symbol is 'Cu...

But it was incredible; she worked so hard. No matter how early I got to the studio, she would always be there before me.SoI called my doorman and asked them one day, I say, "Does Madonna call here and ask you guys has Mr. Rogers left so she can make sure she gets t...
Depending on the initial condition of the metal, it may be necessary to physically remove dirt, rust, mill scale, paint, etc. After cleaning, the metal should be handled with latex or nitrile gloves. Fingerprint and residual oil contamination may show up as a stain on the finish. Preheating...
Why are molten metal chlorides used as electrolytes rather than using other molten salts? Why do methylated spirits evaporate faster than water? Why does water have high entropy? Why is fractional distillation more efficient than simple distillation? Why is ice less dense than liquid wate...
Why does crushed ice melt faster than the same mass of ice cubes? If 50 g of ice at -5 degree C is mixed into 300 g of water at 60 degree C in a completely insulated container, what is the final equilibrium temperature of the water? Why did we ...
As the temperature is increased, molecules of liquid move at (faster or slower) speeds. Does the temperature in a piece of matter increase or decrease if the average energy per particle increases? Ice has a(n) ___ entropy than that of liquid water. 1. lower 2. equal 3. h...
