2010年1月27日 · Then the only way that the original math is meaningful is if both values are differences in temperature, and in that case the result is zero degrees celsius. To argue otherwise would be to make similar additions in other units ambiguous, since (for example) each of those '2m' might be measured from anywhere.

2022年12月23日 · Yes so 0 degrees is the boundary. The energy of the atoms is just right to form a solid lattice and also barely enough to slide past each other as liquid water. My thought is that notall atoms have the same kinetic energy so depending on their exact kinetic energy they’ll either be in solid(if not too high to break loose) or in liquid(if too ...

2018年9月2日 · In Celsius there is a 100 point difference between Freezing 0 degrees and boiling 100 degrees. In Fahrenheit there is a 180 point difference, freezing 32 degrees and boiling 212 degrees. So each 1 degree of Celsius equals 1.8 degrees of …

2023年1月4日 · Hi, I believe by definition, Celsius scale is defined with absolute zero at -273.15°C, and the triple point of water at 0.01°C. However, what does it mean to say that water freezes at 0°C. Is there actually anything physically interesting at all at 0.00°C ?

2013年1月17日 · Yes. Ice at 0 degrees C is at a lower energy state than liquid water at 0 degrees C. If you cool liquid water to exactly 0 degrees C, but immediately stop, the water is perfectly fine existing at 0 degrees C as a liquid. But if you take any more energy away from it, the loss of energy is shown not as a temperature change but as a phase change.

Zero plus zero is still zero. Therefore, zero degrees Celsius would still be 32 degrees Fahrenheit.

That means, the zero of their scale doesn't actually correspond to zero- aka 0 degrees doesn't mean "there's no heat." But Kelvin is a ratio scale- that is, 0 Kelvin is truly the absence of heat (otherwise known as "absolute zero"). So, if you convert 0 C to K, divide that in half, and then back to C, you get your answer.

2017年8月7日 · For every substance, there is a non-zero amount of energy that is required to transition from one phase to another. This energy is called Latent heat . Ice requires ~334 joules per gram to transition from ice to water, and releases that amount in the reverse process.

2021年12月31日 · Pure water freezes at 32 degrees Fahrenheit. The second you add something to it, it will lower the freezing point so that it no longer freezes at 32 degrees. For food you put in the freezer, it's not pure water unless you eat only ice.

2022年2月9日 · The common Celsius and Fahrenheit scales we use are adjusted to temperature ranges that are convenient to human use, but that does not change the fact that they are still measures of energy. 0 Celsius (the temperature at which water freezes) is not, in fact, the zero energy level. That comes at 0 degrees Kelvin, also known as -273 degrees ...
