Why does water expand when it goes from a liquid to a solid? Why is water vapor concentration on the rise? Why does evaporation lower the temperature of a liquid? Why does hyperopia happen in water? Why does water evaporate faster than alcohol?
How does the height to which water is lifted in a capillary tube relate to adhesion and the weight of water lifted? A 1.4 cm^3 air bubble forms at the bottom of a lake, where the pressure is 6.6 atm and the temperature is 4.4^{\circ}C. If the bubble starts floatin...
wave process, the liquid can flow to the top side of an assembly. When this happens, the temperature on the top side of the board may not be high enough to evaporate the solvent. A similar problem can happen with hand soldering, due to the differences in application control among ...
So what does this have to do with evolution and why haven't other species involved intelligence like us? The most prominent example in this case is related to polysialylic acid (PSA) addition on neural cell adhesion molecule 1 (NCAM1). NCAM1 is a cell surface adhesion protein on...
Everyone hates a puncture. There’s never a good time. But try to imagine it costing you a big bonus at work or even the chance to etch your name in to the history of the sport? Given punctures are so costly to riders and teams I’m still surprised they happen so often. But the...
So, how exactly does its physical property change? When the filament absorbs water, they react with each other. The filaments are polymer — until water molecules break up all the secondary molecular bonds and change them into monomers, and this is also the reason why wet filaments are ha...
to repair the air ducts in your home that may have developed leaks. Note that over time, it may get too hot for extended periods and lose its adhesion when used for ductwork. Plan a more permanent solution so you don’t have to get up in your attic every year to perform new repairs...
Good adhesion can make or break the performance of a properly baked Teflon™ coating. The life of a coating can be directly related to the steps taken in cleaning and providing a good surface to adhere to. Find out the best substrates, proper surface preparation materials, and processes ...
Answer to: Consider a pencil partially immersed in a cup of water. Looking from above, why does the pencil appear to be bent? By signing up, you'll...
Water forms into a drop on a leaf and hangs down, but it does not drop. Is this an example of cohesion, adhesion, or both? Explain. Explain the importance of the oil drop experiment. Why does ice float in water even though ice is just melted water? Explain surface tension us...
