What is the change in entropy when a) 100 g of icc is melted at 0 C b) 100 g of water is vaporized to 100 C Use the values for each step to calculate the change in entropy when 100 g of ice at 0 C Explain why water spontaneously freezes to form ice...
For the process H2O(g) H2O(l) at 1 atm and 100 C, the change in entropy is: a) positive. b) zero. c) negative. Explain why water spontaneously freezes to form ice below 0 degree C even though the entropy of the water decreases during the state transition...
this water freezes in the cracks, but when water freezes, it expands quite a bit, which means that it prize cracks open, gradually, making them wider and breaking off a little bits in the process.Now, this thought freeze cycle can happen as many as two hundred times in a single year....
Explain why it is important to determine the Rh of a pregnant woman? What are the consequences of a tubal pregnancy? Why does water expand when it freezes? Give an explanation on why ice floats. Why do spontaneous abortions occur?
Moments after supercooled water freezes, a strange kind of spring-like ice is born. The process involved, which researchers have only now seen for the first time, could help explain how clouds, which contain millions of supercooled water droplets, make rain and affect Earth’s climat...
As you may have discovered, water is an almost unique solid because it expands to begin with when it freezes. In short, not everything fits neatly into our ideas of solid, liquid, and gas and not all solids, liquids, and gases behave in a nice, neat, easy-to-explain way. The ...
Magmatic intrusions can produce strong local stress perturbations and induce seismicity, which vary with time, as the intrusion propagates, thickens, deforms, bends and/or freezes70,71,72,73,74,75. The stress induced by such intrusions (dikes or sills) is spatially heterogeneous. For example, ...
Ever since the days of Aristotle, people have made the counterintuitive observation that hot water sometimes freezes faster than cold water. In modern times, the observation has been named the Mpemba effect after Erasto Mpemba, an elementary school stude
Why the surface of a liquid act like a stretched membrane? Explain why a body of water freezes from the top down rather than from the bottom up. Explain why the viscosity of a liquid decreases with temperature that is, how might increased temperature reduce the effects of cohesive forces...
Discuss why the temperature of a substance remains relatively constant during the freezing of liquid to solid. Explain why water spontaneously freezes to form ice below 0 degree C even though the entropy of the water decreases during the s...
