How much is 1kg TNT?
The complete conversion of 1 kg of matter into pure energy would yield the theoretical maximum (E = mc2) of 89.8 petajoules, which is equivalent to 21.5 megatons of TNT.
How much is a megaton of TNT?
1,000,000 tons
contrast, is frequently expressed in megatons, each unit of which equals the explosive force of 1,000,000 tons of TNT.
How many tons of TNT is a supernova?
The prodigious amount of energy (approximately 10(51), or approximately 2.5 x 10(28) megatonnes of TNT equivalent) and momentum associated with each supernova may even have helped to shape galaxies as they formed in the early Universe.
How much energy does 1kg of TNT release?
4.6 million Joules
TNT has an energy density of 4.6 million J/kg. This means that setting off one kilo of TNT releases 4.6 million Joules of energy, which is enough to raise the temperature of a liter of water by about 1,100 degrees Celsius — or equivalently, to shoot that same liter of water about 470 kilometers straight into the air.
How many grams is a full stick of dynamite?
Form. Dynamite is usually sold in the form of cardboard cylinders about 200 mm (8 in) long and about 32 mm (1+1⁄4 in) in diameter, with a weight of about 190 grams (1⁄2 troy pound).
How many tons of TNT was Hiroshima?
15,000 tons
The bomb was dropped on Hiroshima, Japan, August 6, 1945, at 8:15 AM. A B-29 dropped the bomb from 31,000 feet. The bomb exploded about 1,500 feet above the city with a force of 15,000 tons of TNT.
How many tonnes of TNT was Hiroshima?
15 thousand tonnes
On this basis of comparison, the Hiroshima bomb was of about 15 kilotons – that is, of 15 thousand tonnes of TNT equivalent – and that at Nagasaki was of 25 kilotons (ca.
How many tons of TNT was the Hiroshima bomb?
Is a megaton a million tons?
Megatonne, abbreviated as Mt, is a metric unit equivalent to 1 million (106) tonnes, or 1 billion (109) kilograms.
