Which of the following changes has a decrease in entropy? (3 points)

1.) 2LiClO3 (s) —> 3O2 (g) + 2LiCl (s)

2.) N2O4 (g) —> 2NO2 (g)

3.) C6H6 (l) —> C6H6 (s)

4.) C2H5OH (l) + 3O2 (g) —> 2CO2 (g) + 3 H2O (g)

It is no 3 a solid has the least entropy and here it changes from liquid to solid unlike 1,2,and4

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.
