At various times it has been estimated anywhere from about 12 kilotons to 20 kilotons, I believe the most accurate current estimate is about 13 kilotons.
The temperature of the atomic bomb of hiroshima was 300,000 degrees centigrade.

The first atomic bomb used in war was dropped on Hiroshima, Japan. The delivery method was via an airplane named the 'Enola Gay'.
A pure fission atomic bomb with a yield of a megaton or more is theoretically impossible. The problem is that the chain reaction would happen spontaneously before the device could even be completely built and the bomb parts would melt, resulting in a fizzle and killing everyone building it.The first fusion atomic bomb (commonly called a hydrogen bomb) was tested in 1952 as Ivy Mike and had a 10 megaton yield. The highest yield pure fission atomic bomb ever built was also tested in 1952 as Ivy King and had a 500 kilotons yield.
'Little Boy' the atomic bomb used on Hiroshima weighed 8,900 pounds whereas 'Fat Man' , the atomic weapon used on Nagasaki weighed 10,200 pounds .
The temperature of the atomic bomb of hiroshima was 300,000 degrees centigrade.
"Fat Man", the Atomic bomb that was dropped on August 6, 1945 upon the city of Hiroshima, Japan had a blast yield of 21 kilotons.

An Atomic Bomb I think.
They are the same kind of bomb: bombs that derive their energy from the atomic nucleus. It just depends on design and how much of the design yield is from fission or from fusion. Pure fission bombs cannot be built with yields above 1 megaton, but including some fusion the theoretical yield is unlimited.However considering mission, construction costs, size limits, etc. it is usually more practical to build low yield bombs that are part fission part fusion than to try to build high yield bombs of either type.The lowest yield nuclear bomb tested was the US Davy Crocket at 10 tons yield, the highest yield nuclear bomb tested was the USSR Tsar Bomba at 52 to 58 megatons yield (depending on method of measurement). Both were part fission part fusion designs, although the designs were obviously very different: the Davy Crocket was almost entirely fission yield, the Tsar Bomba was over 95% fusion yield and generated the least fallout per kiloton yield of any nuclear bomb detonated in the atmosphere.
It was both: an atomic bomb using uranium as its fuel.
You are confused, a nuclear bomb is a general name covering both "atomic bomb" and "hydrogen bomb". A hydrogen bomb is typically higher yield than an atomic bomb, although it is possible to design very small low yield hydrogen bombs for special purposes that have lower yield than "typical" atomic bombs. However for "typical" hydrogen bombs their yield is roughly 1000 times the yield of a "typical" atomic bomb.
