## What happens to the missing mass during a fusion reaction?

The mass of the products of a fusion reaction is smaller than the mass of its reactants. The difference or “missing mass” is converted into energy in accordance with Einstein’s equation E=mcÂ˛. Because c is very large, a small amount of missing mass turns into a large amount of energy.

## Why does the sun lose mass as it goes through the fusion process?

If the Sun is constantly losing mass via nuclear fusion, how come it’s not getting any smaller? The Sun gets its energy by crushing together hydrogen and other atoms until they fuse together. By Einstein’s famous equation E = mc2, this energy output leads to a loss in the Sun’s mass of over 350 billion tonnes each day.

## What happens to the missing mass in the sun’s core?

The second way the Sun loses mass is through nuclear fusion. The Sun fuses hydrogen into helium in its core, producing its life-giving glow over billions of years. As the Sun loses mass its gravitational pull on the Earth weakens over time. As a result, Earth is receding slightly from the Sun.

## What happens to the small amount of mass that gets lost during fission or fusion?

The mass difference is converted into energy which is why fusion reaction release energy. In such fission reactions the sum of the masses of the reaction products is less than the mass of the original nucleus. This mass difference is converted into energy which is why fission reactions release energy.

## How efficient is a hydrogen bomb?

So even though a thermonuclear reaction gives off an impressive amount of energy, the proton-proton chain is less than 1% efficient. So it takes 327kg of hydrogen to produce 50MT of energy by using a thermonuclear reaction ( Proton-Proton chain). Of that 327kg, only 0.712% or 2.33kg is converted to energy.

## How much hydrogen is in an H-bomb?

According to wikipedia, high yield nuclear weapons produce something like 5 megatons per metric ton of material, which would mean the Tsar Bomba had about 10,000 kg of hydrogen. That is 2.3 kg mass converted to energy, but a fusion reaction only converts about 0.7% of the starting mass to energy.

The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies. Residual radiation was emitted later. Roughly 80% of all residual radiation was emitted within 24 hours.

## How long did Nagasaki still radioactive?

The atomic bomb that detonated over Hiroshima used Uranium-235, while the Nagasaki bomb had Plutonium-239. The half-life of U-235 is 700 million years, while that of Pu-239 is 24,000 years.

## How did Hiroshima recover so quickly?

Hiroshima had been completely destroyed by the A-bomb, but gradually electricity, transportation, and other functions were restored. The people collected any unburned materials they could find and began rebuilding their homes and their lives.

two years

## Was Chernobyl or Hiroshima worse?

“Compared with other nuclear events: The Chernobyl explosion put 400 times more radioactive material into the Earth’s atmosphere than the atomic bomb dropped on Hiroshima; atomic weapons tests conducted in the 1950s and 1960s all together are estimated to have put some 100 to 1,000 times more radioactive material into …

## Are there still birth defects in Hiroshima?

Birth Defects among the Children of Atomic-bomb Survivors (1948-1954) No statistically significant increase in major birth defects or other untoward pregnancy outcomes was seen among children of survivors. Monitoring of nearly all pregnancies in Hiroshima and Nagasaki began in 1948 and continued for six years.

## Why did Hiroshima victims die after drinking water?

First, I checked with Hiroshima Peace Memorial Museum and found a reference which suggested that permitting the gravely wounded to drink water could result in releasing their tension and hastening their death. A soldier then surprised him by saying, “If you give water to the victims, they’ll die.”
