Which action represents an increase in entropy?

green food coloring diffusing through cookie dough

one end of a rod of steel getting warmer while the other end gets cooler

Green food coloring diffusing through cookie dough.

Explanation:

Entropy is a physical quantity for an equilibrium thermodynamic system that measures the degree of organization of the system, or that is the ratio of an increase in internal energy to an increase in temperature of the system.

When the green dye diffuses through the cookie dough there is an increase in entropy, that is, there is an increase in system disorder at the molecular level, where a change in cookie dough occurs.

B. green food coloring diffusing through cookie dough

Explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
