Question

an irreversible process takes place by which the entropy of the universe increases by 1.63 j/k. if the temperature of the environment in which the process occurred is 295 k, how much energy (in j) was made unavailable for useful work as a result?

Answer 1

According to the given statement 480.85 Joules energy was made unavailable for useful work as a result.

What is an irreversible process?

When a process begins, it is said to be irreversible if the system and its surroundings do not immediately return to their prior state.

Briefing:

The universe's entropy is S = 1.63 J/K.

T = 295 K is the environment's temperature.

The energy that is not usable for work is calculated using entropy and temperature as

ΔS = Q/T

1.63 J/K = Q/295K

Q = (1.63 J/K)*(295K)

Q = 480.85 J

The energy unavailable for useful work is 480.85 Joules.
