The temperature at the surface of the Sun is approximately 5,300 K, and the temperature at the surface of the Earth is approximately 293 K. What entropy change of the Universe occurs when 6.00 103 J of energy is transferred by radiation from the Sun to the Earth?

The entropy change of the Universe that occurs is 19.346 J/K

Explanation:

Given;

temperature of the sun, = 5,300 K

temperature of the Earth, = 293 K

radiation energy transferred by the sun to the earth, E = 6000 J

The sun loses Q of heat and therefore decreases its entropy by the amount

The earth gains Q of heat and therefore increases its entropy by the amount

The total entropy change is:

Therefore, the entropy change of the Universe that occurs is 19.346 J/K

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
