Almost there, JJ ... :clap: :clap: You've found the standard! So, what is twice as cold as the freezing point of water?

Nope, not twice the coldness of absolute zero (this doesn't exist in reality, of course!!), but of the freezing point of water.

186.575 k is twice as cold as the boiling point of water
136.575 k is twice as cold as the freezing point of water

Absolute zero is 0 degrees kelvin. Zero degrees centigrade is 237.15 degrees more than absolute zero, thus twice as cold as zero degrees centigrade is -136.575 degrees centigrade.
(Not sure if this is the answer to the original one or the second one :huh: :huh: )

Jungle Junkie, Bushmom :clap: :clap:

That's what I was looking for! The absolute standard - below which no heat exists, and so which cannot get colder - is 0 degrees Kelvin, or -273.15 degrees Centigrade. Therefore, twice as cold is indeed halfway to absolute zero from the given quantities, i.e. boiling point of water at 373.15 K and freezing point of water at 273.15 K, therefore being 186.58 K and 136.58 K respectively.

:D :D

Place six crosses on a noughts-and-crosses (tic-tac-toe) diagram so that not one of the rows or diagonals contains three next to each other.

Sorry cannot get the lines in, but I think you can see what I mean. You did not say one cross in each square!!!!!

You're right that I never said one cross per square, and I should have because this is what I am trying to achieve (oversight, sorry). Can you then figure it out with one cross in a square, such that you place six crosses in the nine squares, and not get three in any one line or diagonal?

There was an avid hunter who enjoyed hunting around a dam near his farm. He always hunted on the eastern side of the river where wild animals were not abundant. However, the western side was filled with wild animals, easy hunting grounds. So why does the hunter avoid the western side?
