The Sun outputs about 3.846 x 1026 Watts. A)
How much mass is being converted into energy every second in the
Sun’s core? About 0.7% of this mass becomes energy through
the fusion of hydrogen to helium: 4H Ă He +Îł . B) What mass
of hydrogen is being converted into helium every second?
C) Astrophysicists speculate that there is about 9.626 x
1028 kg of hydrogen left in the core (about half of what
the Sun began with). How many more years will the Sun be able
to fuse hydrogen assuming the same rate?
