What is the entropy change in the environment when 5.0 MJ of energy is transferred thermally from a reservoir at 1000 K to one at 500 K

The entropy change in the environment is 3.62x10²⁶.

Explanation:

The entropy change can be calculated using the following equation:

Where:

Q: is the energy transferred = 5.0 MJ

: is the Boltzmann constant = 1.38x10⁻²³ J/K  

: is the initial temperature = 1000 K

: is the final temperature = 500 K

Hence, the entropy change is:

Therefore, the entropy change in the environment is 3.62x10²⁶.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
