The core of the sun has a temperature of 1.5 × 107 k, while the surface of the sun has a temperature of 5930 k (which varies over the surface, with the sunspots being cooler). treat the core of the sun and the surface of the sun as two large reservoirs connected by the solar interior. nuclear fusion processes in the core produce 3.8 × 1026 j every second. assume that 100% of this energy is transferred from the core to the surface.
(a) calculate the change in the entropy as, in joules per kelvin, of the sun every second

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

no

explanation:

no i dont know how to solve this you should probably try to google the answer

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.
