How much mass was converted to Energy?

A. 70g B. 700g C. 7 kG D. 70 kG E. 700 kG

Mass equivalent m=E/c2 = 15x4x1015/(3x108)2 = 6x1016/9x1016=670 g

1 KeV = 103 eV Kilo 1 MeV = 106 eV Mega 1 GeV = 109 eV Giga 1 TeV = 1012 eV Tera 1 PeV = 1015 eV Peta 1 EeV = 1018 eV Exa 1 ZeV = 1021 eV Zeta

1 eV = 1.6 x 10-19 J 6x1018 eV = 1 J

E=m0γc2 For particle at rest γ=1 so E=m0c2

Or m0=E/c2 ie for a proton m0= 938 MeV/c2

E=m0γc2 For particle at rest γ=1 so E=m0c2

Or m0=E/c2 ie for a proton m0= 938 MeV/c2

700g of mass Converted in much much Less than a second

200 g of mass Converted per year

Windsor Ontario – 580 megawatt natural gas-fired power plant. What is the mass equivalent of the energy this plant generates per year?

580 megawatts = 6x108J/s x 3 x107 s/yr = 1.8 x1016 J/yr E=mc2

m=E/c2 =1.8x1016J/(3x108m/s)2

=(1.8x1016/9x1016)kg = 200g

a. 200 g b. 2 kg c. 20 kg d. 200 kg

Anti-matter The Energy source of the future?? Suppose there was an easy way to store anti-matter. And suppose the reaction (matter+anti-matter)->Energy could be controlled and harnessed.

Would anti-matter be a viable energy source??

With 100 grams of anti-matter?? Can we replace

NO! (Sorry Scotty) Antimatter: Energy Source of the Future and Always will Be.
