WebMar 13, 1998 · 3. How much energy is produced when the Sun converts 1 kg of mass into energy? For how many years would this energy keep a million 100-Watt light bulbs burning? (1 Watt = 1 Joule/sec) 4. How much energy is produced when the Sun converts 1 kg of hydrogen into helium? (HINT: The entire kilogram IS NOT converted to energy!) WebAug 14, 2024 · Figure 20.9.2: (left) The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second. (right) The proton-proton chain dominates in stars the size of the Sun or smaller.

WebMar 8, 2015 · The sun is a big ball of plasma comprised of protons and the number of proton-proton fusion reactions to helium occurring in the suns core is estimated to be 3.6×10^38 per second. Now the mass of one single proton is ~1.67x10^-24 grams and doing the multiplication of these two numbers gives the 600 million tonnes per second … WebExpert Answer. 1. Energy generation in the Sun, The principal energy-producing reaction in the Sun fuses four protons into a helium nucleus. Four protons, each with mass 1.0079 amu, form a helium nucleus with mass 4.0026 amu (1 arnu = 1 atomic mass unit = 1.66 x 10-22 kg). (1) How much mass in kg is lost in the creation of a single helium nucleus? WebAnswer (1 of 7): Indeed! Overall it loses mass, but not by much. There are two primary ways that the Sun loses mass: the Solar Wind and nuclear fusion. The Solar Wind is a result of the Sun’s magnetic field flinging charged particles (electrons, protons, etc.) into space. Some of these particles... buyin g amotorcycle dealer financing vs bank
