Why is it that when you make ice cubes, they form faster when you pour lukewarm to cool water in the tray, and form slower when you pour colder water into the trays. What is this process called?
Also, related, why is it that if you have a steam hose filled with pressurized steam behind a nozzle, and you spray it onto a pipe encrusted with ice in -30 degree weather, the ice on the frozen pipe will melt faster when you hold the nozle 6-12 inches away from the pipe, and slower if you hold the nozzle 1-3 inches away from the pipe? What is this process called,when the steam is hotter slightly further away from the nozzle?
Brief descriptions of hows and whys of these questions woul;d be appreciated, thanx.
