Cracker Jack said:The absolute zero temperature which has a numerical value of - 273.16ºK is as previously stated the thermal point at which no molecular motion is possible, therefore at this temperature, no thermal energy is produced.

You say 10 degrees Fahrenheit [10ºF] or 10 degrees Celsius [10ºC]
but with Kelvin, there's no 'degrees' or º symbol. Just ten Kelvin [10 K].
I think they are referring (not very clearly) to absolute scales of measurement. Do a web search for "scales of measurement", and you should find many pages that explain this. Absolute scales are also called ratio scales.kim555 said:I have to Identify a research issue, opportunity, or problem that uses data that has absolute zero measurements, and I do not understand what zero measurements means. Can anyone help?
panjandrum said:So off I went to Google "absolute zero measurement", and rather to my surprise it came up with about 100 hits. Apart from the first link, to this thread, most of these are gobbledygook to me. So I wondered why? AHA! - Absolute Zero walks a fine line between thrash metal and death metal, ...
SaiYanNara got some things wrong, though. Absolute scales can have negative values. For example, the m/s scale for velocities is absolute, and a velocity can be negative.Diskfly69 said:SaiYanNara,
I thought the same thing about Res/341...only because I AM currently in Res/341 and am working on that very assignment! Your post is a BIG help...Thanks!

Technically, velocity is a vector.nycphotography said:Technically, a velocity can't be negative, but a velocity vector can have a negative sign (direction). Or some such. I think. Maybe.
Scalars can be negative. It's absolute values that cannot. Speed is an absolute value; that's why it can't be negative.panjandrum said:I think, being pedantic, which is dangerous when I only think, that speed is scalar, and therefore cannot be negative; velocity is vector, and therefore can be negative.
