Question

What is the change of entropy for a heat engine using 500.0j at 20.0c

Answer 1

1.71 J/K
hope it helps :D!!

Answer 2

The formula to find change in entropy is given by :

`Change in entropy = (Q)/(T)`

where Q is change in heat and T is temperature.

We are given Q = 500 joule and T = 20 degree C

Plugging these values in the formula,

`Change in entropy = (500)/(20)`

We get change in entropy = 25 J/Celsius.
