Scientists in Finland have cooled rhodium atoms to a 10th of a billionth of a degree above absolute zero. On the other hand, an absolute maximum temperature would require there to be a limit to the amount of energy you can give to a particle. As far as we know, there is no such limit. Although the speed of light is the universal speed limit ...
Answer. Temperature is basically a measure of how much energy each particle has got or each direction a particle moves in. And so, you can pretty much all the energy away from something and you can't take any more energy away, and so, there's a minimum temperature as an absolute zero. But certainly, in any normal idea of physics, anything we ...
Answer. There is no highest possible temperature that you can achieve. On a microscopic scale temperature is approximately the amount of energy each atom has. You can have a lowest possible temperature because you can have no energy at all. But you can give as much energy as you like to a particle but it will still just keep getting hotter and ...
After all this work they finally found the theoretical lowest temperature you can cool water to without freezing is -55 celsius. This might seem quite academic, but supercooled water is very important in many types of cloud, and has been discovered there at -40 celcius, and understanding how water behaves at these temperatures will help ...
This theory predicted that the maximum temperature that a superconductor could function at was about 30K (-247°C). This meant that there was somewhat of a shock in 1986 when there a superconductor discovered which became superconducting at 35K and others rapidly developed at 92K (Yittrium Barium Copper Oxide) with the current record set at ...
Answer. The speed of sound does depend on temperature and it is slower at colder temperatures, so it can sound different. Deep down, sound is the vibration of molecules and if you've got a lower temperature and you meet them, they just vibrate a bit slower.
The highest wind speed that we've measured here at SANAP in the last 7 years was 52 metres/second at a height of 10 meters. Temperature-wise, the colder it gets, the more extreme the wind. At the moment today, the wind speed is around about 7 meters/second and the maximum temperature is -2°C. What is quite interesting when comparing Antarctic ...
Answer. Dave - The main reason why things heat up when they hit the Earth's atmosphere is they've got huge amounts of kinetic energy - they're going incredibly fast. When they bash into the Earth's atmosphere, most of the heating is actually because the air they bash into hasn't got time to get out of the way, so the air gets compressed; and ...
Usually, when things freeze - in other words turn from a liquid into a solid - they shrink or get smaller.This is because, normally, if you make something hotter, it vibrates more. When it vibrates more, it tends to take up more space, so it tends to expand.So, logically, if you cool something down, then the particles should move more slowly ...
Eva - One recent development has been the suggestion that producing sperm at a lower temperature might actually help with the process of fertilisation. Bill - When sperm that have been produced and stored at the slightly lower temperature associated with external testes are released into the vagina, they encounter a warmer environment and this ...
