Physics 02
Okay, today in class, Mr Lim asked us blog about two questions. I'm going to do the first one in this post. Question: Why do ice stick to our finger. From my personal experience, the ice doesn't stick to our finger every single time. I'm not sure how it happens too. But I do noticed that the ice cubes tend to stick to our finger when our fingers are wet, or when we use our tongue. Let's find out why (: According to a website named The Naked Scientist, it explains that this is because the ice then re-freezes the liquid on your finger. And, the fact is, the ice cube doesn't get stuck to us, we get stuck to it. Interesting? Because the liquid is a fluid and it has got into all the nooks and crannies on your finger it then freezes solid and will form a very tight bond between your finger and the frozen surface, the ice. You get stuck to the surface. If it’s an ice cube –it’s okay because there’s enough heat flowing through your fingers However, those eskimos living in Antartica might not be that lucky. Because their temperature is c.-70 degree celsius, once they get stick to the ice, it might be permanent and might not be able to remove it. If not, the eskimo might get an serious injury from the ice. This is so as their body doesn't warm up. reference: http://www.thenakedscientists.com/HTML/content/questions/question/2265/ That's why ice are sticky (:
