Nuclear energy Flashcards
1
Q
When referring to fission remember to refer to the …
A
Nucleus not the atom
2
Q
Spontaneous fission
A
When fission happens for no apparent reason
3
Q
Induced fission
A
When the nucleus is hit by a neutron and fission occurs
4
Q
Comparison of fusion to fission in terms of energy
A
Fusion has a greater energy yield per kg of fuel
5
Q
Amount of energy released in nuclear processes can be calculated by
A
E=mc^2 where
E = energy in Joules
m= mass lost in kg
c = speed of light - 3x10^8
6
Q
How to carry out energy released calculations
A
Ensure that atomic and ,ass numbers are conserved if not add neutrons/ beta particles
Find actual mass from table before and after reaction
Take away after from before then plug that in as m in E=mc^2
