There is NO temperature at all below 0 (zero) Kelvin, because that is the ABSOLUTE zero point, absolute zero, the point at which there is an total absence of all thermal energy. Energy can be negative, the same as mass and eg. volume of matter.
Physicists and nuclear scientists create atomic bombs.
One of the problems with water in a thermometer is the effect of capillary action - the column of water tends to "stick" to the sides of the thermometer and create a U-shaped surface at the top. This makes it very difficult to read the thermometer. Previously mercury was considered to be a good medium for thermometers, but this has been discontinued due to the health risks from a broken mercury thermometer; the current medium in thermometers is dyed ethanol or methanol.
Because it took that many years for scientists to create andprove Hofmann's discovery.
The temperature could increase as the reaction progressed. Higher temperatures would create a faster reaction.
there are alot of chemical mixtures that create exothermic REACTIONS, but no chemical in particular. my favorite chemical reaction is thermite. (alluminum powder, iron(ii) oxide) temperatures reach 9000 degrees!
No, it is not true; but some experiments were realized at Munich recently but the meaning is another. And the problem is not new: in the years 1950-1952 some British physicists (Purcell et alii) proposed a theory of negative temperatures on the Kelvin scale.See the link below.
1593 and it is call The Galilean Thermometer.
It will implode and create a black hole. not really, it'll just measure the heat..

Scientists use data from the past to create a timeline.
No.
To test hypotheses, scientists create experiments.

No. Those are just folklore.
